Formula Intolerance HELP!

My daughter is a little over 5 weeks old and for the most part seems to be fine on the Enfamil infant (yellow) that my older daughter was on last year too. She's gaining weight, has plenty of wet diapers and at least 1 dirty per day. I'm concerned though if it is right for her or if I am just being super Helicopter mom. (I swear I have Post Partum Anxiety this time). She doesn't always spit up but she has had 2 instances once this morning and once last week on Thursday where she literally soaked us both with how much she spit up/vomited.

Anyone else have a hungry hippo that overeats and then vomits? Or is she maybe not tolerating it well?
