Hi, my 7 mth old baby have difficulty going to sleep. He sleeps in a yao lan but I still have to pat him to sleep with him inside for a long time. He can sleep through the night (abt 10 hrs) but he can't seem to nap long in the afternoon. Usually I will put him to sleep about 3 times during the day but each time he napped less than an hour. most of the time only nap for half an hour then wake up already. He does nap for longer hours occasionally but that seldom happens. I think he is not getting enough sleep coz he is always very cranky during the day but I just can't get him to sleep longer. How do I make my baby sleep longer in the day?
