worst days !!

He has been climbing in and out of the cot like nothing. In fact, once he climbed it once, he kept doing it like as if he practised for some exam or something. He is so quick now, he is in the cot within a few seconds and out the next second. We had a lot of trouble settling him to sleep which we have never had before. Last night we couldnt settle him until after 10pm, he kept climbing out. This afternoon (sat) he kept climbing onto our double bed and then SLEPT there for 2 hours. We are very close to thinking of buying either a bedrail(again) for the cot, buy a toddler bed or go straight to a single bed.
