In the second month, your baby may be able to make cooing sounds, follow objects and hold their head up for short periods. Some babies at this age can recognise voices and smile responsively. At three months old, most babies can hold their head steady and recognise faces, some babies start to laugh and may be able to bring their hands together.

Your baby's firsts are amazing to watch. But from their first smile to their first words, every baby is different - so it's important that you don't compare your baby's milestones to other children's. However, it can be helpful to know when you can expect to see them reach their first milestones, so if your little one needs a helping hand along the way, you can encourage their development. In the fourth month, most babies can bear weight on their legs and coo. Some babies can reach out and grasp objects and might start to cut their first tooth.
