So about 2weeks ago we switched formula from Sam’s club members mark infant premium (that’s equivalent to enfamil neuropro) to similac 360 total care.

The reason we switched was because my baby would fuss sometimes during a feed. We either thought it was the bottle/nipple or that she didn’t like the formula. We switched the formula because we had the similac on hand. That seemed to work! But we also tried new bottle brands after that and I think that helped too.

But now it’s been 2 weeks and she’s been having watery diarrhea for most of that time. I know it takes time for babies to adjust to new formula but now that it’s been 2 weeks, I’m not sure if we should try switching to a different formula (possibly the old one) at this point. she had no poop issues on the old one and only barely started fussing for a tiny bit sometimes - so part of me thinks it was just the bottle she didn’t like but who knows for sure!

Any suggestions? Should we keep going with the similac and give it more time, go back to the old one, or try a completely new formula? What would you do?
