Transition from Pack & Play to Crib

Kamalika

My little one has been sleeping in his pack and play from when he was 2 months old but now since he can roll both sides and sit up on his own and also can get into a crawling position and start crawling, the pack and play seems to be not safe as he can always try to stand up and in that case will fall out of the pack and play.

I need suggestions on when should we must put the baby in crib. Also please share suggestions on buying crib.
