#asktheexpert my baby doesn't sleep much is it a cause of concern?When he was a newborn he would sleep very less like only for half an hour then he would get up. This is continuing till now . He sleeps only half a hour three times a day and at night he would wake up every one hour . He is gaining perfect weight and is active and healthy but he isn't crawling yet.He is going to be 8 months old in next week
