Quoting dee0331:“ I have a few questions.... 1. How much spit up is too much? I keep reading things that say it's rarely ... [snip!] ... sure if this was all of them. I do plan on talking to my ped. about everything, but I'm just looking for your opinions/input.”
My daughter sucked my pinky until she discovered her fingers around 3 months old. Now she is a hardore finger-sucker.
The redness/soreness on your one breast could be mastisis, or another type of breast infection - I'd maybe call the doc.
If your baby seems to be spitting up everything she's eaten, or doesn't seem to be thriving, then it's a problem. Your pedi might switch her formula.
You might want to experiement with different paci's, b/c even though my daughter wasn't big on paci's, she would take a certain kind better than others.
good luck, mama!
