Sleep regression already ?!

All of a sudden (as in the last 5-6 days) my daughter has become a MUCH worse sleeper...

Since we brought her home she’s pretty much only ever eaten once around 3 am (with the exception of her first 2 weeks) which has been such a blessing because our 3 year old would eat every 2 hours

Well now, she has been waking up at least 3 times a night, sometimes to eat, sometimes just to babble. I am EXHAUSTED because it’s never predictable.

Anyone else’s baby seem to be going through the 4 month sleep regression early? I read that sometimes this can happen

Helppp
