Breastfeeding

This baby is my third but first while working. My older two I stayed home for the first year while the breast feed but this time around we needed the extra money so I started work when baby was two months old. My sister in-law watches our kids while we work and she has a child she still breastfeeds also. Last week she decided to breast feed my baby because he was screaming but she didn’t have a bottle made. She had milk thawed out but not in his bottle warmed up. I don’t really know how to feel about it because it wasn’t necessary. She had milk for him and could have given him a pacifier while she warmed it up but decided instead to just breast feed my baby instead
