How has your partner adjusted to your new baby?

What does he do to help? Especially if your breastfeeding, how else is he involved?

Looking for advice, something to compare to.

My fiancé has not adjusted well, I don’t think he’s bonded with the baby and I do 100% of the work even though he only works 3 days a week. There’s some days he doesn’t even hold him once.

Thanks in advance!
