Here is the problem, I have a 15 month old, and I think she has probably no more than 4 months left in her cot - because she is so tall! It is a cot rather than cot bed.
I would rather keep her in the cot for now, if only to restrain her! But wondering when you put yours into a bed. Should I just buy a bigger cotbed, or will it be time for a bed by then? Also, did you go for a toddler type bed or straight to a single bed?
Or shall I just make her scrunch her knees up for a bit 
thanks
