My little man is going to be 4 months old on the 25th. Around 2 1/2 months old I started having to supplement with formula, and now he’s just formula fed. Once we started formula feeding he immediately slept through the night, I mean like slept at least 8 hours no problem. Well now, for the 3rd night in a row, he won’t sleep 😡😡 I’ve kept the same routine, he’s sleeping in a glider which he’s always slept in, my room isn’t too hot or cold, there’s no light, like nothing has changed. I’ll get him to sleep, and it doesn’t matter if he’s been asleep for 20 minutes or an hour, within an hour of putting him down he’s screaming. And it’s always right when I’m falling asleep, he starts kicking his legs, flailing his arms around, overall just freaking out. He’s not sick or anything, not constipated, not hungry because he usually has a bottle right before bed. As far as I can tell, there’s nothing wrong with him. My days are spent taking care of him and working 8 hours, so by the time it’s time for bed I’m exhausted, and my husband is no help whatsoever at night. So I need to figure out what the hell is going on before I lose my mind. Any ideas??
