Does anyone have one? Would you recommend for a 5 & half month old that is starting to roll and needs somewhere secure to nap during the day. Is it sturdy, or would DS trying to roll topple it over? Been putting him on sofa up until now, watched closely by me, but as he gets more mobile, I'm worried he might fall off or roll into corner and suffocate. He is so well trained that cot means night, he won't go in it during the day .
Thanks
