Formula fed: increased spit up? 12 weeks

Ke

Hi all,

My 12 week old has been formula fed her whole life. She’s always had Enfamil and done really well with it. But it seems like the last few days she spits up A LOT more (more volume and more frequently).

We haven’t increased her feeding frequency or amounts. Nothing has changed to cause this.

She’s not fussy. I don’t feel like she’s in pain or anything.

Normal? Any suggestions?
