Baby development at 4-5 months: what’s happening
Over his first few months, your baby has learned to know your voice, remember what you look like and understand that you respond when he needs you. At about five months old, he’s starting to form a stronger attachment to you. He’s also got to know other close family members and carers well, and understands who they are.
Your baby will turn to you when she hears your voice, and she might even respond to her name or another sound, like a bell ringing.
Your baby is showing more emotion – blowing ‘raspberries’, squealing, making sounds like ‘ah-goo’ and even trying to copy the up-and-down tone you use when you talk. He might smile and talk to himself (and you!) in the mirror. He’s also starting to show emotions like anger and frustration. Instead of crying he might growl or whinge.
Your baby really enjoys reaching and grabbing everything around her – dangling rings, rattles, toys, small blocks and more. She can hold things in her hand using her palm and index finger.
At this age, your baby might also:
- drop something – for example, a spoon – and turn his head to look for it (but he probably won’t look down for it just yet)
- roll from back to tummy as well as from tummy to back
- sit up with support around his hips and behind his bottom and lower back
- put his fingers in his mouth and start getting interested in what you’re eating – this interest will grow over the coming weeks.
