My son is six weeks old and wants to be held constantly. He won't sleep unless being held at night or in the day. If he falls asleep in my arms and then I set him down, he wakes up crying within minutes, if not immediately. It's starting to interfere with the amount of sleep he's getting and I think it's the cause of his recent fussiness. He needs his sleep so I'm doing the best I can to be with him but I do need a break. Any suggestions?
