My son is 1 year old and has started walking but from last few days he is falling too much which was not happening earlier. What could be the reason?

A. Hello good afternoon !! Initially due to fear the baby walks very slowly and takes a gap for step to step ,but afterwards due to walking fast and lifting the leg fast (not keeping the sole of the feet fully on the floor) they keep on falling and it is normal. Take necessary precautions like using a head cap or baby helmet,using floor mats helps.
