My husband and I are seriously struggling with our LO's sleep regresssion. From about 3 months old to 5 1/2 months he was sleeping 8pm-7am. Sometimes he would wake a bit and fuss but never really wake up. Since mid-November (when we introduced fruits and veggies) he's been up every night. We try to soothe him but after about 10-15 minutes we feed him. But then I can't get him to go back down. He's up for 1.5-2 hours overnight every night now. Any advice? Anyone else going through this? He has no teeth and I don't feel any trying to make their way through either.
