Have you checked for teething? My little one is definitely teething right now. Sometimes if we are having a rough or fussy day, I just give her a cup of milk and snuggle for a while, and that helps reset.
I agree with teething! My toddler was like this last week and I thought it was pregnancy related too but it was just her back molars coming in. Hang in there, for us it lasted about 3 days❤️
