My baby is too active and he started rolling over in only 1.5month's and and took crawling position in just 3rd month. He never play peacefully without crawling or even in play gym or crib (palana) he starts crawling. My worry is as he has very fast physical growth , many times falls on floor and gets his head hurt so how can I stop him from crawling and falling on floor or should I always take him on my lap so that he would stop crawling in such early age to avoid head injury?
