I am posting this here in the hope that someone out there might understand why I feel upset by this.
I had a hellish start to breast feeding, it was very painful for the first three months and I came very close to giving up. I made it through and breast feeding is very important to me.
My SIL mix feeds which is totally her choice, I don't have an issue with it, it is just not for me. We have been staying with them and this morning she told me that my DS had been drinking her DD's formula while I was out of the room.
I feel really upset by this. Logically I know it doesn't matter that much - apparently he threw it away after tasting it anyway. I just don't feel good about it. I didn't want him to have formula ever. It also feels a little disrespectful. I would never let her DD have something that she had never had before without checking it was ok with her mother first.
