9 week old super fussy!

Hi all!

So my baby girl was born 5 days late and all of a sudden at the start of week 9 she’s become SUPER fussy, not taking naps, and not sleeping well.

She hit her 5 week leap early and at 8 weeks it was like nothing happened. She was super happy and is naturally a very happy baby. She did have a cold last week and only mild sniffles now but is totally fine. No issues. Normal temp. Still smiling and cooing, just fussy at times and won’t sleep well. I mean she was going 7-8 hours between her bottles she was doing so well!!
