Baby Not Laughing
The short answer
Most babies laugh for the first time between 3 and 4 months, but some perfectly healthy babies don't laugh until 5-6 months. If your baby is smiling socially, making eye contact, and showing joy through facial expressions and body language, they may simply express happiness differently - not every baby is a big laugher.

By Age
What to expect by age
0-3 months
Laughter isn't expected yet during the first 3 months. Your baby is focused on social smiling (which usually appears around 6-8 weeks), cooing, and learning to engage with faces. These social skills are the foundation for laughter. Some babies may chuckle by the end of this period, but most haven't reached that stage.
3-5 months
This is the typical window for first laughs. Laughter often emerges in response to physical play - gentle bouncing, tickling, or silly sounds. Some babies are more reserved and may grin broadly without laughing out loud. What's most important is that your baby shows social engagement and pleasure in your interactions, not necessarily an audible laugh.
5-7 months
Most babies are laughing by this age, though some laugh rarely. If your baby smiles, coos, and is socially engaged but simply doesn't laugh much, this may just be their temperament. However, if your baby doesn't smile, doesn't seem to enjoy social interaction, or is very passive, it's worth discussing with your pediatrician.
7-12 months
By this age, most babies laugh during play and social games like peekaboo. A baby who has never laughed by 7-8 months and also shows limited social smiling or engagement should be evaluated. However, a baby who laughs rarely but is otherwise happy, interactive, and meeting other milestones may simply have a more serious temperament.
What Should You Do?
When to take action
- Your baby is under 4 months and smiling socially - laughter typically comes after social smiling is well established.
- Your baby smiles and shows excitement through kicking, arm-waving, and facial expressions but just doesn't laugh out loud much - some babies express joy more quietly.
- Your baby laughs in some situations (like during physical play) but not in others - this is normal selectiveness.
- Your baby was a bit late to social smile but is now smiling regularly - laughter often follows a few weeks after consistent smiling.
- Your baby is over 6 months and has never laughed or chuckled, even briefly.
- Your baby rarely smiles and doesn't seem to enjoy social interaction or face-to-face play.
- Your baby doesn't respond emotionally to your voice, singing, or playful sounds.
- Your baby seems unusually passive or withdrawn - they don't reach for you or show excitement when you approach.
- Your baby was laughing and smiling and has stopped - any regression in social-emotional responses warrants prompt evaluation.
- Your baby over 6 months shows no social smiling, no laughter, no eye contact, and no interest in people - this cluster of concerns should be evaluated promptly.

Related Speech Concerns
Accent vs Speech Disorder in Bilingual Toddlers
When toddlers grow up hearing more than one language, they naturally blend sounds, patterns, and accents from both languages. This is normal and healthy, not a speech disorder. A bilingual child may pronounce some sounds differently than monolingual peers because they are learning the sound systems of two languages simultaneously. True speech disorders affect both languages equally, while accent influence appears only in specific sounds borrowed from one language to another.
Ear Fluid Affecting Baby's Speech Development
Chronic or recurrent middle ear fluid (otitis media with effusion) can temporarily reduce hearing by 15 to 40 decibels, which is like hearing through water. During critical periods of language learning, this muffled hearing can impact speech and language development. If your baby has frequent ear infections or persistent fluid, discuss the potential speech impact with your pediatrician.
Will Ear Tubes Help My Child's Speech?
Ear tubes (tympanostomy tubes) can restore normal hearing by draining persistent fluid from the middle ear. Many children show speech and language improvement within weeks to months after tube placement, particularly if hearing loss from fluid was contributing to their speech delay. However, ear tubes alone may not resolve all speech delays, and some children benefit from speech therapy alongside tube placement.
Baby Failed Newborn Hearing Screen - What Now?
Failing a newborn hearing screen does not necessarily mean your baby has hearing loss. Many babies who fail the initial screen pass on follow-up testing. However, it is critical to complete follow-up testing by 3 months of age. If hearing loss is confirmed, early intervention by 6 months of age leads to significantly better language outcomes.
Baby Using Jargon but No Real Words
Jargon babbling, which sounds like your baby is having a conversation in a made-up language, typically appears between 10 and 14 months and is a positive sign that your baby is learning the rhythm and melody of speech. Real words usually emerge from jargon over the following months. If no real words appear by 16 to 18 months, a speech evaluation may be helpful.
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.
