My baby is 9 months old. I’ve read the safe sleep 7 and bedshare with him every night. At what age is it safe for babies to sleep with an overnight caregiver who’s not the parent(e.g., grandma, aunt, friend)? He’s walking already and I honestly feel ok if they wanted to bedshare with him to make it easier when he wakes throughout the night. He’s strong and I don’t see much risk as long as they’re sober.
