I am 4ft 11 and my DD is currently 10mo and still on the highest level in her cot - she can't pull herself up yet so not an immediate problem...however...
When she does, I have a problem, lowering the base level will mean I can't lay her down / get her out let alone moving it down to the lowest level - it doesn't have a dropside.
Has anyone else had this problem? What did you do? The cot turns into a cotbed.
