At least cots are supposed to be for sleeping. Elijah seems to think cots are for playing. He'll be showing all his tired signs, practically fall asleep on the way to the cot, then as soon as he's down, grin and giggle and wave his arms about. Consequently, we have an overtired Bugalugs and a stressed Mummy.
He also thinks cots are for practising his gross motor skills, pushing with his feet to get out from under the covers and end up at the other end of the cot. This is day 3 of being in the cot and we haven't had a successful nap or overnight sleep yet.
