The sound of a baby's laugh, and how to hear more of it
Why babies start laughing around three to four months, simple play ideas that invite giggles, what to mention to your health visitor, and the gift of joy in a tired season.

You blew a raspberry on your baby's tummy, or pulled a silly face, or sneezed loudly, and out it came: a proper laugh. Not a coo, not a gurgle, but a real, hiccuping chuckle that made you both laugh harder. For many parents, it is one of the sweetest sounds of the first year.
When laughter arrives
Most babies start laughing out loud somewhere around three to four months, building on the social smiles that began in the early weeks. At first it might be a single surprised "Ha!" By five and six months, many babies laugh readily at games they know, at older siblings, and at the same silly sound repeated for the twentieth time.
Laughter is more than fun. It shows your baby is paying attention, recognising patterns, enjoying surprise and connecting with people they love. Every giggle is a little piece of learning.
Play ideas that invite giggles
You do not need to buy anything. Try these during calm, alert times, when your baby is fed and rested:
- Peekaboo. Hide your face behind your hands or a muslin, then reappear with a cheerful "Boo!" Keep it gentle at first.
- Tummy raspberries. A soft blow on the tummy during a nappy change is a classic for good reason.
- "I'm going to get you." Slowly walk your fingers up from their toes to their chin, building suspense, then a little tickle.
- Silly sounds. Pops, clicks, animal noises, an exaggerated sneeze. Babies love the unexpected.
- Copy cat. When your baby squeals or babbles, copy it back. Then wait. They may do it again just to hear you.
- Gentle movement. Holding your baby securely, sway, dip slightly, or "fly" them close to your face. Avoid throwing them in the air or any shaking.
- Songs with actions. Rhymes with a big finish, such as clapping or a tickle at the end, teach your baby to anticipate, which is half the fun.
Watch your baby's signals. Turning away, arching, rubbing eyes or fussing means it is time to slow down. Laughter can tip into overwhelm quickly at this age, so a quiet cuddle is part of good play too.
Around this age you may also notice
- Squeals, coos and longer babbling "conversations"
- Reaching for toys and bringing them to the mouth
- Holding the head steady and pushing up on the arms during tummy time
- Recognising familiar faces and sometimes being shy with strangers
Every baby develops at their own pace. Mention it to your health visitor or doctor if, by around four months, your baby does not smile at people, does not seem to respond to loud sounds or voices, does not follow moving things with their eyes, or seems very floppy or very stiff. Also mention it at any age if your baby seems to lose skills they had. Asking early is always fine.
What laughter does for you
Parents of three to six month olds are often still very tired. Night feeds may continue, and some of you are navigating a return to work, a slow birth recovery, money worries or a lonely season. A baby's laugh does not fix those things, but it can lift your head for a moment.
Do not feel guilty for needing that lift. Joy is not frivolous. Proverbs 17:22 speaks of a merry heart doing good like medicine, and there is real wisdom in letting yourself enjoy these moments fully, even on a hard day. Put the phone down, get on the floor, and play the silly game again.
When Israel came home from exile, the psalmist remembered it like this:
"Then was our mouth filled with laughter, and our tongue with singing: then said they among the heathen, The LORD hath done great things for them." (Psalm 126:2, KJV)
Your baby's giggle is a small echo of that: a reminder that God gives good gifts, even into tired homes. Some of you waited a long time for this child, or carry grief for a baby you never got to hear laugh. Both joy and sorrow can sit together in your heart, and God is near in both.
Making a laughter memory
Try recording a short voice note or video of your baby laughing this week. On harder days ahead, in the toddler years, the teenage years, or simply a long Tuesday, you will be glad to hear it again.
A prayer of thanks for laughter
Lord, thank You for the sound of my baby's laugh. Fill our home with more of it. On the days when I feel heavy, let these small joys lift my eyes to You. You have done great things for us, and I am grateful. Amen.
