I have one ds, 2.8 years who still sleeps in a cot bed with the sides up.
I haven't taken them down yet as he hasn't figured out how to climb out, so as far as I am concerned the need hasn't yet arisen.
However, I have had more than a few comments now from visitors and family members suggesting that he is FAR TOO OLD to be sleeping in a cot.
AIBU? Surely, it's better he isn't running about the place causing havoc at bed time any earlier than he needs to be?! I am of the mind - all in good time! On a side note, this is also my approach with potty training, he is no where near ready and has absolutely NO interest so I have decided not to push it quite yet. However the raised eyebrows are coming thick and fast for that too...
Sigh, is it me... AIBU?
