I have a 3 yr old and a 17 month old. I co-slept with both of them from the start.
Obviously as tiny babies, dh and I were very aware that they were in the bed, we made sure they were high up above pillows and duvets etc, made sure they wouldn't overheat or get squished, and wouldn't have had them in bed with us if either of us had been drinking.
Recently though, dh and I seem to wake up and blearily take stock of who ended up in which bed, and with who. Dd(3) creeps in unnoticed and while she sometimes sleeps up at the pillow end with us, sometimes she snuggles down at the bottom of the bed. Ds has to be lifted from his cot to come in with us, so technically one of us knows he's in the bed, but he's a lousy sleeper and we often have to think quite hard to work out when he got in with us and who brought him in.
It all seems quite safe to me as both children are big and strong enough to throw the duvet off them if they're hot, and I just can't imagine dh or I squashing them as (a) they're too big, and (b) we're both so used to having children in with us.
I thought I'd ask MN in case I get lots of faces and tales of 2 yr olds suffocating due to lax parenting.
What do you think? Should we still be actively and consciously 'Safe Sleeping' or does there come a point when you don't have to think much about it, and have we reached that point?
