Is it wrong that I want to tell my wife I would prefer it if she breastfed our son for atleast at the start.
Why hate formula milk. Doesn't your wife want to breastfeed your son?
I think there is a lot of estrogen in formula.
It is rude and wrong to tell your partner what to do. If she doesn't you can order breast milk online or from a group.
I can order it online for free.
It's great that you want what is best for your son, however be mindful of the pressure that this puts on your wife. Telling her to breast feed if she's choosing not to might be inconsiderate of her wishes for her body.
