Weird Sleep Behavior in an 11 Week Old

I agree with the moms who suggested reflux. My babies all had it- the prescription made all the difference. BTW, one of my babies also had reflux, but never actually spit up. She could be sleeping better at night from sheer exhaustion. Be glad it's not the other way around, like it was for me. I was up all night, which wouldn't have been so bad if she were my first and I could sleep during the day, but I had 2 other children to care for so I spent the large part of a month fighting to keep my eyes open. The doctor wanted us to try switching formula 1st- which didn't work and only prolonged my DS's misery- and mine as well. I was about ready to drop the baby off at the Pedi's house for the night so he could see what it was like ;)

My 3 month old son has reflux and had sort of been doing the same thing. A prescrip has helped.

There is more noise, during the daytime.

Gas?

Feeding enough?

Too stimulated before nap?

Over-tired?

Waking up screaming... tends to be gas.
But at night she does not do this?

My daughter as a baby, would wake too. She was sensitive to noises and anything. Even a toilet flushing down the hall... would wake her and she'd jolt awake, screaming.

Does your Toddler make a lot of noise when baby is napping?

Maybe she is uncomfy in her swaddled position? My babies did the screaming too, I think there hands or feet would fall asleep and they would get that "pins and needles" feeling. Thats painful to me, so I could only imagine how it is for a newborn!

Reflux? Does she do a chewing motion like to is working something back down?

My grandchildren had reflux. We finally found that they slept better in their car seat. It keeps them in a more upright position. It's also much like being swaddled. We fastened them in with the harness and then covered them with a blanket. We set the car seat in their crib. They often slept this way until they'd outgrown the seat.
