Really want to know! Pushchair says 6months+ and he's only 20 weeks but on the 98th centile and has grown out of the pram and much too heavy for the sling. Pushchair attachment (loola comfort bebe if it matters) is backward facing and tipped back quite a way, so his chin's not on his chest or anything. Was planning to just use for short trips to be on the safe side, but he falls asleep beautifully in it -before this he would only nap on me, so it's such a relief.
Currently at the pool waiting for him to wake up so we can go swimming. Should I wake him instead of letting him nap in the chair? Am I damaging his spine?
