She’s not crying, she just fussing or straight up awake
If she fusses during feeding she might have gas pain. But when my baby was a newborn she hated diaper changes and fussed during feedings because of my fast milk flow and has reflux. Sometimes they don’t like diaper changes cuz of the cold wipe. Warm it with your hands or wipe warmer. Change the diaper fast cuz of the cold weather.
At this age you gotta put them to sleep. They can’t sleep on their own yet. Sleep training starts at 4-6 months. Honestly babies sleep bad especially with the Moro reflex as a newborn. You can swaddle them or put them in a baby swing to settle a bit. Or stroller walk.
Driving around helps!
The bed thing might be growth sprout. But the diaper thing was it differet/watery/what color? Is she breathing ok?check her folds; neck, thighs, underarms... Look for any irritations. Touch different parts of her body like ears, belly, neck, ... if the cry gets louder it could be pain. Don't worry we've all been through this. You're doing a great job! We're all in this together🤗💕
