12 weeks fussyness

[LaurenSarah22]

So my LO has been so fussy and crying from about 12 weeks 4 days of age. She's normally such a happy baby but atm one minute she will be smiling then she will suddenly start crying. Today ( 12 weeks 6 days) she's drinking so much more!! I've upped an oz but even that doesn't seem enough for her. She putting everything in her mouth and chewing on her fist all the time.

Is this a growth spurt you think ??

I want my old baby back !!!

It is very probably a growth spurt. I'd feed her as often as she wants, wigs often, and always make sure there's a little left in the bottle so you know she's had enough

Could she be teething?

Sounds like teething to me. My boy is 18 weeks and has been like that for a few weeks now ... hope it's over soon!!
