My Ds is 10 months, he was swaddled since birth then we transitioned into crib and sleep bag just before 6 months, but I've noticed he really likes to cuddle his blanket during naps (always supervised) and I think it may play a part in his lack of sleep? I never give him one at bed time because I wouldn't be able to supervise I'd be asleep, but would it be okay at 10 months now or still to early? I've tried a Muslin but doesn't work, but when he wakes up and I settle him with his blanket his straight back to sleep. Then I have to take it off him.
