What to Expect in Your Child’s First 90 Days of ABA Therapy

A preschool-age child sits on a soft living room rug with colorful stacking toys while a female therapist and the child's mother sit nearby at floor level, smiling and gently engaging in play in a bright, cozy home setting with navy, pink, and blue accents.

If your child is about to start ABA therapy, the first 90 days will usually focus on getting to know your child, building trust, setting practical goals, and noticing early wins. In most cases, this stage is less about dramatic overnight change and more about creating a strong, thoughtful plan that fits your child’s needs and your family’s daily life.

For many parents, this season brings a mix of relief, uncertainty, and a lot of questions. You may be wondering what sessions will actually look like, how long it takes for goals to come together, and whether the early weeks are going the way they should. That is completely normal.

Quick Answer + Key Facts

Most families can expect the first 90 days of ABA therapy to move through a few clear stages: preparation, assessment, rapport-building, goal-setting, and early progress review. A BCBA leads the assessment process, oversees the treatment plan, and adjusts goals as needed. An RBT often handles the day-to-day therapy sessions. Parent coaching helps connect what happens in therapy to real life at home.

Quick Summary

  • Before sessions start: The team gathers background information, confirms logistics, and learns about your child’s routines, strengths, and current challenges.
  • Days 1 to 14: Early sessions often focus on observation, baseline data, and helping your child feel comfortable with the therapist.
  • Days 15 to 30: Goals start to take shape, and therapy becomes more connected to communication, transitions, and everyday routines.
  • Days 31 to 60: The team watches for patterns, small wins, and areas where the plan may need to be refined.
  • Days 61 to 90: Families usually have a clearer sense of priorities, progress, and what the next phase of care will focus on.

One of the most important things to know is that visible change can take time. Good early ABA therapy is built on careful observation, family input, and a treatment plan that reflects what your child actually needs, not a one-size-fits-all checklist.

Before Therapy Really Gets Going

Before therapy feels fully underway, there is usually a short setup period. That can include intake paperwork, scheduling, assessment appointments, and conversations about your child’s routines, communication style, strengths, and stress points.

At this stage, the team is usually collecting information, not expecting major change yet. For a younger child, that may mean talking through favorite toys, comfort items, snack routines, and tricky transitions. For a school-age child, the conversation may focus more on after-school routines, independence, flexibility, and participation at home or in the community.

For families in Georgia, logistics can vary a bit depending on scheduling, authorizations, and insurance details. Even so, the bigger goal is the same: helping the care team understand your child well enough to build a useful, realistic starting plan.

S: Set the baseline

During the first one to two weeks, a strong ABA team is learning how your child responds in real situations. That includes communication patterns, preferences, stress triggers, attention, transitions, and the level of support your child needs during daily routines.

Baseline data is simply starting-point information. In plain language, it helps the team understand what life looks like right now so they can measure whether support is helping over time.

For toddlers, that may mean watching play engagement, imitation, comfort with a new adult, and early communication attempts. For older children, the team may pay closer attention to transitions, self-help routines, following directions, and participation at home or in the community.

This part can feel slower than some families expect, but it matters. A clear baseline helps the team set better goals and avoid guessing.

T: Trust before teaching

One of the most important parts of early ABA is pairing, which means helping your child feel safe, comfortable, and willing to engage with the therapist. That is why the first sessions may look more play-based, flexible, or observational than some parents imagined.

You might notice smoother handoffs, more comfort during sessions, less resistance to certain routines, or stronger engagement during play. Those are not small details. They are often the foundation that makes later teaching more effective.

If you want more context for why early sessions can look this way, this article explains why play-based ABA may feel different from what parents expected.

A: Align goals to daily life

Once the team has enough information, the BCBA should begin shaping goals that connect to real family life. The most useful early goals usually focus on the moments that matter most day to day, such as transitions, dressing, mealtimes, communication frustration, play, following directions, safety, or participating in routines.

For a younger child, that might mean asking for help instead of becoming overwhelmed, moving between activities more smoothly, or joining simple play. For an older child, early goals may involve bedtime routines, flexibility when plans change, self-care, or better participation in home expectations.

The point is not to create a generic list of ABA goals. It is to make sure therapy is working on challenges that genuinely affect family life.

R: Read the right progress signals

By days 31 to 60, and often more clearly by days 61 to 90, families can usually start to notice meaningful early signs of progress. Those signs are not always dramatic. Sometimes progress looks like better tolerance, more communication attempts, smoother transitions, faster recovery after frustration, or stronger participation in routines that used to feel hard.

The team should also be reviewing data, session notes, and patterns over time, then adjusting the plan when needed.

  • Myth: Progress should be obvious right away.
  • Reality: Early gains are often practical and easy to miss if you are only looking for big, dramatic change.
  • Myth: If sessions look playful, not much is happening.
  • Reality: Play, rapport, and motivation often create the conditions that make learning possible.
  • Myth: Progress should move in a perfectly straight line.
  • Reality: Some skills improve faster than others, and that does not automatically mean something is wrong.

T: Take the next step with the team

As the 90-day mark gets closer, most families should have a clearer sense of the treatment plan, the communication rhythm, and what the next review period will focus on. Your observations matter here. It helps when you can share what seems easier, what still feels hard, and what you are seeing outside of session time.

It also helps to understand who does what. The BCBA typically handles assessment, goal selection, clinical decision-making, supervision, and plan updates. The RBT usually runs sessions and records day-to-day data. If those roles still feel fuzzy, this guide to what a BCBA does in your child’s ABA program can make that distinction clearer.

After day 90, therapy should feel less like a startup phase and more like a working system that can keep building on what the team has learned.

What Parents Can Do at Home Without Adding More Stress

The best support at home is usually simple, steady, and realistic. Share what you are noticing. Let the team know when a transition is getting easier, when a routine is still hard, or when your child shows a new skill outside of session.

It can also help to keep routines predictable where you can, practice one or two strategies the team has already modeled, and ask for examples that fit your real day. Parent support does not need to look perfect to be useful.

FAQ

What should parents expect during the initial assessment in ABA therapy?

Parents can expect the team to learn about their child’s current skills, communication style, routines, triggers, strengths, and areas of concern. That information helps the BCBA build goals that fit everyday life.

How do therapists build rapport with children in the first few weeks?

Therapists usually build rapport through pairing, preferred activities, low-pressure interaction, and careful observation of what helps the child feel comfortable. Early sessions may not look like the highly structured version of therapy some parents first imagine, and that is often completely appropriate in the beginning.

How is progress measured in the early stages of ABA therapy?

Early progress is usually measured through baseline data, session notes, direct observation, and BCBA review of patterns over time. In the first 90 days, progress may show up as increased tolerance, better participation, smoother routines, and more communication attempts, not just major skill breakthroughs.

What are realistic milestones in the first 90 days of ABA therapy?

Realistic milestones may include easier transitions, improved engagement, stronger communication attempts, and a clearer family understanding of what helps. For a toddler, that might look like more imitation or smoother routines. For an older child, it may look like better flexibility, stronger independence, or more consistent participation at home.

What happens after the first 90 days of ABA therapy?

After the first 90 days, the treatment plan is usually refined based on what the data, the family, and the therapy team have learned. Some goals may expand, some strategies may shift, and parent coaching often becomes more targeted.
