My baby is 3 weeks and 4 days old. For the past 5 days she has only wanted to poop, eat, and sleep. She used to be up for a couple of hours refusing to go to sleep (she wouldn't be tired or show tired cues) and now If shes awake more than it takes to change her diaper and feed her she cries until you rock her to sleep. This is completely different from how she was the day before. She basically changed overnight. She wakes herself to feed every 2ish hours and has no problems eating but she wants to go right back to bed after eating and having a diaper change. She has no fever either.

She went from never crying, barely fussing to all of a sudden being tired all the time and crying a lot.

Does anyone know if this is normal or if I should mention it to my doctor?? I see her doctor on the 4th but should I be calling her now???

**I got my Covid vaccine the morning she started to act differently and I only breastfeed her. I don't know if this would affect her**
