Delayed Receptive Language
The short answer
Receptive language is your child's ability to understand what they hear. Most children understand far more words than they can say. If your child seems to have trouble understanding language - not just speaking it - that's an important concern to address early. Receptive language delays can be harder to spot than expressive delays, but they respond well to speech therapy, especially when caught early.
By Age
What to expect by age
By 6 to 12 months, babies should understand some common words and phrases. They typically respond to "no," recognize their name, follow your gaze to look at things, and understand simple routines like "want up?" with arms raised. If your baby doesn't seem to understand any words or respond to simple verbal cues by 12 months, check their hearing first - this is the most common treatable cause.
At this age, children should understand 50 or more words, follow simple one-step commands ("give me the cup"), and point to familiar objects or body parts when asked. If your toddler seems confused by simple requests that other children their age can follow, or doesn't seem to understand common words, a speech-language evaluation is a good idea.
Between 18 and 24 months, receptive language grows rapidly. Your child should understand simple questions, follow two-step directions, and identify many common objects and pictures. If your toddler consistently doesn't understand what you're saying - even when you simplify your language and use gestures - this is more concerning than just having few spoken words. Receptive delays need attention.
By age 2-3, children should understand concepts like "in," "on," "under," answer simple "what" and "where" questions, and follow two-step directions. If your child has trouble understanding age-appropriate language - often looking confused, not following directions that peers can handle, or needing everything repeated multiple times - a comprehensive speech and language evaluation is important.
After age 3, children should understand most of what is said to them in everyday situations, follow multi-step directions, and understand basic stories. Receptive language delays at this age can affect learning, social relationships, and behavior (children sometimes act out because they can't understand what's expected of them). Speech therapy can make a significant difference.
What Should You Do?
When to take action
- Your child understands language well but doesn't speak much - this is an expressive delay, not a receptive one, and has a better prognosis.
- Your toddler ignores you when you ask them to do something they don't want to do - this is defiance, not a comprehension issue, and is age-appropriate.
- Your child follows directions at home where routines are familiar but struggles with new or unfamiliar instructions - context-dependent understanding is normal in young children.
- Your baby is under 9 months and doesn't follow verbal commands yet - receptive language is still emerging.
- Your child is 12 months or older and doesn't seem to understand common words like "no," "bottle," "mama," or "bye-bye."
- Your child is 18 months or older and can't follow simple one-step directions, even with gestures.
- Your child has both limited understanding and limited speaking - combined receptive and expressive delays are more concerning than expressive delays alone.
- Your child seems to not understand any spoken language at any age past 12 months - even common words, their name, or "no" - hearing must be tested and a full evaluation started immediately.
- Your child previously understood language and has stopped comprehending - any loss of comprehension is an emergency and requires immediate evaluation.

My Baby Is Losing Words or Skills
If your child was consistently using words and has truly stopped, this is something to act on promptly. Regression - the genuine loss of skills a child previously had - is different from a normal plateau or a toddler being too busy to talk, and it always warrants a conversation with your pediatrician sooner rather than later.
Baby Not Babbling
Babbling with consonant sounds like "ba," "da," and "ma" typically begins between 6 and 9 months and is an important building block for speech. Babies develop at different rates, but if your baby is not making any consonant sounds by 9 months, a hearing check is a good first step.
Baby Not Laughing at Peek-a-Boo
Most babies start showing delight during peek-a-boo between 6 and 9 months, when they develop "object permanence" - the understanding that things still exist when hidden. If your baby isn't laughing at peek-a-boo yet, consider their age and overall social engagement. Some babies prefer other games, and some show enjoyment through smiles or excited movements rather than laughter. What matters most is whether your baby is socially engaged with you overall.
Baby Not Making Vowel Sounds
Most babies begin making vowel sounds - those lovely "oooh," "aaah," and "eee" sounds - around 2 to 3 months of age. This early cooing is one of the first steps in language development. Some babies are naturally quieter than others, but if your baby isn't making any vowel sounds by 4 months, it's worth checking in with your pediatrician to make sure hearing and development are on track.
Baby Not Responding to Own Name Consistently
Most babies start recognizing and responding to their own name between 5 and 7 months, though consistent response may take until 9 months. It's common for babies to sometimes ignore their name when they're focused on something interesting - this is normal. However, if your baby rarely or never turns when you say their name by 9 months, it's worth discussing with your pediatrician to check hearing and development.
Baby Not Turning to Sounds
Babies typically begin turning toward sounds around 4 to 6 months of age. If your baby isn't consistently looking toward voices or noises by 6 months, it's worth having their hearing checked. In many cases, something as simple as fluid in the ears can temporarily affect hearing, and early identification leads to the best outcomes.
