4 month sleep regression

Sierra

My 15 week old baby is going through her 4 month sleep regression, I’m pretty sure! She’s waking every 2-3 hours when she used to wake only 1-2x a night.... it’s exhausting! I’ve just been feeding her til she’s asleep again, then laying her back down, except during her old “normal” wake time where I change her diaper too.

For those mommas who’ve dealt with this before, how long did it last? How did you get past it? Any tips for a mom who JUST went back to work this week (teleworking thankfully) and is now dealing with this also?!
