Please help this exhausted mama! A week ago my 15 month old started fighting every nap and bedtime.

I used to be able to lay him down awake and he would put himself to sleep. Now I find myself rocking him for hours and he falls deep asleep on me and then the second I put him in his crib he starts SCREAMING. This goes on ALL hours of the night.

I feel like I have tried EVERYTHING to help him. Tried feeding, bottle, Tylenol, CIO, white noise, projectors...etc.

Please, please any tips, advice, know what's going on??? 😭😭😭
