How to convice husband to let me be a stay at home mom.

So any advice would be great. Currently I have a 4 month old and I just recently started going back to work after maternity leave. I do work from home, but I have a pretty demanding schedule where I have to be present for several video meetings and take several calls throughout the day. Due to Covid and stuff we aren’t super comfortable sending my daughter to daycare, especially with how young she is and I’m trying to exclusively breastfeed.

Anyway, I have an agreement with my boss where I’m working less hours, but I’m still overwhelmed with trying to be a good mom and also working.

I’ve brought up being a sahm during pregnancy but my husband wasn’t sure. We make good money, and his job is where we get our insurance. So I’d really like to be a sahm at least until she is 6/7. Any advice on how to get my husband on board?
