I need sleep training tips, tricks and advice! My 16 week old had been fighting sleep ALL night and when I say all night like from midnight-five thirty in the morning of crying, tossing, turning and the crying some more. He will have his eyes closed and just be crying and kicking. I’ve taken him to his pediatrician and he doesn’t have acid reflux or anything he just will not sleep! I put him to bed at 7:30-8 every single night and at 11-12 he wakes up and continues to wake constantly.
