This is very condescending. I’m gonna assume the partner nursed the other times she was with the child, like at night. While we can be overly pedantic about the fact that during the day, the baby was bottle fed with breast milk, people have enough stress around breastfeeding as it is; am i doing it right? Does it still count if I pump during the day? Etc etc.
It's not meant to be condescending, and I've updated my comment slightly to try to clarify that. Thanks for pointing out the tone.
I don't think it's overly pedantic in a conversation about fathers spending time as a primary care taker. I think it's actually fairly on topic.
As I understand it (not a doctor), there is a decent bit more going on with breastfeeding than simply the mechanics of delivering milk. Is there a trade-off being made by bottle feeding a baby? Almost definitely. Is it worth it? Sounds like a topic of conversation we could have.
