My babies are used to me taking them from one thing to another all day...they are not settled doing any 1 thing. I'll try tummy time, they've always hated it...3 minutes later I'll have a screamer...we'll sit up in the bumbo with some toys, that doesn't work for long...rocking, swinging, jumparoo time, reading, singing, mobile. Nothing works for more than a couple minutes and they are unhappy again. They are not hungry or wet,, they do not have anything obviously wrong, they just NEVER settle down. I'm going crazy, I feel like I'm a circus act for them! I know they are overstimulated, they are extremely difficult to get to nap, and their naps are short. I've tried keeping the curtains closed, tv off, no radio...tried white noise...tried letting them try to settle themselves. They work themselves up into a screaming duo. How do I break this cycle? Help!
