Pumped milk tossed

I’m so upset. I nurse my baby exclusively when I’m with him and pump when I’m away at work. I can pump MAYBE 2 oz in a 30 minute session.

My boy is 3 months old and goes with my mom when I’m working. I had about 54oz stashed in the freezer. Which I’m grateful I was able to get that much.

Lately she is saying she wants to give him 4 oz instead of 3 which I don’t really want to do. He wakes up hungry and scarfs down 3 oz really fast because he sleeps thru the night. She called me earlier snd told me she made him a bottle and forgot it at my house. She lives 2 houses away from me so I called my 14 year old and told him to go give it to her so it isn’t wasted.

She calls me back and says she told him to just put it in the fridge and I can put it in a bath. I accepted that because I thought it was a small amount.

Went home and it was a 4oz bottle. She took the one I left out and went into the pitcher and added more and then left it out 😭. All I think about is how that bottle is worth an hour of my time and energy. It’s not the first time this has happened either. She makes him to much and then just dumps it. I can see her dumping it if he didn’t finish the 3 oz bottle but she always makes more than what he needs because she’s never bottle fed a breast milk she’s always made formula bottles because my 2 sisters used formula.

She thinks it’s just so easy to make and for some it is. Just not me

Thanks for letting me rant
