Babywearing meets a need! The newborn needs to be carried a lot. The 2 year old child, much less because he has other capacities of exploration, in autonomy. He will therefore appreciate being carried for a stroll but posed to play on the ground whenever he wants. As long as babywearing is used to meet the needs of the moment, there is no time limit or any particular risk! You just have to be careful to alternate baby's supports by changing position in a sling or turning the head from side to side if baby is sleeping.
