By the third month, your baby has discovered that there's more to life than just eating, sleeping and crying; here's what else you can expect:
Your beautiful baby will be squealing, smiling, gurgling and generally delighting everyone around her.
Her hands will be a constant source of fascination and she will also be playing for longer stretches of time during the day and, hopefully, staying asleep for longer during the night.
If you are not already, begin reading to her as this will help get your baby's ear tuned to language.
Choose board books with large, bright pictures and simple text, as well as books with material such as fur or felt to help stimulate her sense of touch. Vary the pitch of your voice to keep your baby stimulated and interested.
Talking to your baby is also important. Narrate what you are doing in your everyday routine, for example, when changing the nappy or pointing out different foods in the supermarket.
While she won't be able to repeat these back, she will be storing them up in her ever-developing memory bank. Her ability to interact is on the increase and by now she may respond to her face in the mirror or to the sound of your voice.
She will also be able to engage more with other babies, so get out and about and meeting other mums and dads – it will be a chance for you to share your experiences too and let you know that, whatever worries you have, you are not alone.
