Re: Worried Something is wrong...
My formula fed niece and nephew were really, really screamy at night. Breastfeeding has absolutely nothing to do with evening fussiness. I'm pretty sure formula and bottles are not easier when you have to prepare a bottle while your baby screams. It's certainly not easier when SIL is digging through an overly stuffed diaper bag to mix a bottle while I just pop a boob out and only carry a couple extra diapers and wipes in my pack.
I'm glad to hear your baby is well. Don't stress too much about work. Your baby will adjust to the new routine.
