poop...

how do I know if my baby is having stomach issues?

we we're doing more breastmilk than formula, but last week we had to make an abrupt change and now it's far more formula than breastmilk, especially on MWF because I had to go back to work.

she is 9 weeks old today and 6 out of 7 diapers at daycare were poopy and it's been a similar pattern for the past 4-5 days.bshe started daycare on Monday of last week, so the abrupt change happened a week ago today.
