Husband is resentful of my lack of follow through with pumping

Our baby is a bit older now, but we want to have another baby. I said we might both be exhausted in the beginning and argue. He said we only argued in the beginning because of me being wishy-washy with breastfeeding and having a lack of follow through with pumping bottles. He said it was difficult during his shift when I would insist on breastfeeding but be too tired to properly feed him every 2-3 hours. And I was a hormonal mess of course, with no idea what I was doing.

He says we don’t have to talk about it, but if we do, he didn’t like the way I approached the conversation- which is that “of course we were going to have some conflict in the beginning.”

When we discuss managing a baby and toddler together, I have no idea what that looks like yet.
