One of the most common questions families ask is: "How do I know if my child actually needs therapy?" It's a hard question, because every child develops on their own timeline. Some children walk at 9 months. Others walk at 15 months. Both can be completely typical.
But there are patterns worth paying attention to. Certain developmental milestones serve as useful reference points, and consistent delays across multiple areas can be an early sign that your child might benefit from support.
Key Takeaways
Before you dive in, here's what matters most:
- Developmental milestones are useful guidelines, not rigid rules — but consistent delays across multiple areas are worth discussing with your pediatrician.
- Trust your instincts. You know your child better than anyone.
- Early intervention makes a difference. It's better to ask for help early than to wait and see.
- Red flags include limited eye contact, no babbling by 12 months, no words by 16 months, or loss of previously acquired skills.
About This Guide
This guide walks through the signs that therapy may be helpful, organized by developmental area and age.
We'll also talk about the "wait and see" approach and why early intervention almost always makes more sense. For a complete overview of pediatric therapy, start with our main guide: Pediatric Therapy: The Complete Guide for Parents.
Developmental Timelines
The Centers for Disease Control and Prevention (CDC) provides milestone checklists for children from 2 months through 5 years. These milestones represent what most children can do by certain ages. They're not pass/fail tests, but they are useful benchmarks. If your child is consistently missing milestones across multiple areas (communication, movement, social interaction), that's worth discussing with your pediatrician.
6 Months
- Knows familiar faces and begins to know if someone is a stranger
- Likes to play with others, especially parents
9 Months
- May be afraid of strangers and clingy with familiar adults
- Makes a lot of different sounds like "mamamama" and "bababababa"
12 Months
- Is shy or nervous with strangers and cries when mom or dad leaves
- Puts out arm or leg to help with dressing

Communication Red Flags
Communication delays are one of the most common reasons families seek early intervention services. Here are the signs that speech or language therapy may be helpful:
- No babbling or back-and-forth sounds by 12 months
- No single words by 16 months
- No two-word phrases by 24 months
- Difficulty being understood by family members by age 3
- Difficulty being understood by strangers by age 4
- Limited use of gestures (not pointing, waving, or showing objects to share interest)
- Difficulty following simple directions ("Come here," "Give me the ball")
- Loss of previously acquired language skills at any age
It's important to distinguish between speech delays (difficulty producing sounds clearly) and language delays (difficulty understanding or using words). Both can be addressed with speech therapy, but they're different issues.

Physical & Motor Red Flags
Physical and occupational therapy address delays in movement, coordination, and daily living skills. Here are signs that PT or OT may be appropriate:
Gross Motor Concerns (PT)
- Not sitting independently by 9 months
- Not walking independently by 18 months
- Walking on toes consistently after age 2
- Frequent falling or difficulty with balance
- Unable to climb stairs with support by age 2
- Significant differences in strength or movement between the two sides of the body
Fine Motor Concerns (OT)
- Difficulty holding a crayon or pencil by age 3
- Unable to use a spoon or fork independently by age 3
- Difficulty with buttons, zippers, or snaps by age 4
- Avoids activities that require hand coordination (puzzles, building blocks, coloring)
- Significant difficulty with handwriting or cutting with scissors in kindergarten

Sensory Red Flags
Sensory processing challenges are common in children with autism, ADHD, and sensory processing disorder (SPD). Occupational therapy is the primary treatment. Signs include:
- Over-responsive to sensory input: Covers ears at normal sounds, refuses to wear certain fabrics, avoids messy textures, extreme distress during haircuts or nail trimming.
- Under-responsive to sensory input: Seems unaware of pain or temperature, constantly seeks intense sensory experiences (crashing, spinning, jumping), doesn't notice when hands or face are messy.
- Difficulty with transitions or changes in routine (extreme rigidity)
- Meltdowns that seem disproportionate to the situation
- Difficulty sitting still or maintaining attention
Sensory challenges often overlap with other developmental concerns. For a deeper dive into sensory processing issues, read: Signs of sensory processing disorder in children.
The "Wait and See" Trap
One of the most common pieces of advice parents hear is: "Let's wait and see. Some kids are just late bloomers." And yes, it's true that children develop at different rates. But here's the problem with waiting:
Early intervention is most effective when it happens early. The brain is most plastic and responsive to therapy during the first few years of life. Waiting six months, a year, or longer can mean missing a critical window.
"I kept hearing 'boys talk later' and 'Einstein didn't talk until he was 4.' So I waited. By the time we finally got an evaluation, my son was 3 and a half and significantly behind. I wish I'd trusted my gut sooner."
— Parent of a child with a speech delay
Here's the truth: if you're concerned, it's worth getting an evaluation. Evaluations don't commit you to anything. They give you information. And if your child doesn't qualify for services, that's great news. But if they do qualify, you've just saved yourself months or years of waiting.

Trust Your Instincts
You know your child better than anyone. If something feels off, if you have a nagging sense that your child is struggling in ways that other children aren't, trust that instinct. Parents are often the first to notice developmental differences, sometimes long before pediatricians or teachers do. Your concerns are valid. Your observations matter.

FAQ
Frequently Asked Questions
What if my pediatrician says to wait?
You can ask for a referral to early intervention services (for children under 3) or request a developmental evaluation anyway. You don't need your pediatrician's permission to pursue an evaluation. Trust yourself.
Will my child be labeled if we get an evaluation?
Evaluations are confidential, and a diagnosis (if one is given) is a tool for accessing services, not a permanent label. Many children receive early intervention services and go on to thrive in school without any ongoing support.
What if my child only has delays in one area?
That's common and still worth addressing. A child might have strong communication skills but struggle with motor coordination, or vice versa. Therapy can still be very helpful even if delays are isolated to one area.
