Transition out of crib

I recently jus shifted my toddler (2years old) out from his bedcot to a mattress on floor . Reasons: he has grown too long n tall for the bedcot n he is so tall that if he attempts to lean forward while standing at the bedcot , he looks like he might jus fall out ! So for safety reasons , we transited him to a mattress on floor . So far so good
