Formula changes

Hello Mamas!

I recently gave birth and started my baby on enfamil instant formula because my breasts milk took some time to kick in. Well yesterday we couldn’t find that particular one but another one same brand but this one was specifically for gentle ease ( gas, fussiness, etc ). How ever now baby is having more frequent passes in greater amount. Her poop on the other one had seeds in it this one doesn’t. However she seems to be hungry a lot more now. Is the new milk ok? Is it better to have the looser poop or what?
