She's 1 week old and just nursed for 30 minutes and actually spit up twice after burping. She takes a paci so I gave that to her but I'm worried it will mess up my supply, she only wants to suck a couple times then falls asleep. She is basically wanting to use me as a paci, should I let her or should I nurse? She has plenty of dirty and wet diapers so I think she's eating plenty.
