Hi my son is in his 17th week. Recently, he has been waking every hour or hour and a half especially after 2am. I would feed him for about 20 mins and he would fall back asleep. He is also an early riser, so I can barely get thru some mornings! I've been wondering when and how I can wean him off some of the night feeds. He weighs 5.5kg (about 12 pounds), and feeds every 2-4 hours during the day. Any advice?
