All typically developing babies and young children have the same developmental milestones. Babies develop at different rates but should reach the milestones in the same order. If your baby has a hearing impairment, he won’t hear people speaking, which means he might not respond to your voice and other noises in the way you’d expect. As he gets older, you might notice that his speech and language aren’t developing like other children’s.
As a guide, here is what you’d expect in a typically developing baby. If your little one isn’t doing these things, it might be a good idea to talk to your GP or maternal child and family health nurse.
From birth to four months:
Your baby should startle at a loud noise, turn her head or move her eyes to locate the source of the sound. If she’s upset, she should calm down when she hears your voice.
From 4-8 months
Your baby should notice sounds around her, smile when spoken to, babble, and understand simple words like ‘bye-bye’.
From 8-14 months
Your baby should respond to her name, say simple words like ‘mama’ and ‘dada’, copy simple sounds, and use her voice to get attention from people nearby.
From 14-24 months
Your child will start to develop vocabulary, understand and follow simple instructions, and put two words together.
