My DD is currently 21.5 months old and is still too short to climb out of the cot but I was wondering if I should transition her to a bed while she can't reach the door knob. I have a few friends who have had their kids transition and the biggest issue they have is that their kids keep opening the door and coming out. I thought if I transition my daughter while she can't reach maybe she won't go through that phase.

Good idea to transition now while she can't reach or is it better to leave her in the cot for as long as possible?
