At this age, between you and your baby, there are already many exchanges and complicities.
Your baby is good with his hands and body. It holds now seated, like doing somersaults, flying with dad or mom on the horse's knees.
You can take the opportunity to teach him all game rhymes and hands (like the traditional "puppets") ... do not forget to end the session by magnificent applause associated with the classic:
« Bravo » !
It is also at this age that you start making games of hide and seek ... by hiding your face behind your hands or concealing his favorite teddy behind your back ... memorable parts of laughter in perspective ...
In addition, this will help your baby to realize that objects do not disappear forever ... but they may reappear very quickly!
