How often is your baby breastfeeding?

J • 30. Married. Mom to a beautiful 1 yr old boy

My lo is 15 weeks today and is breastfeeding constantly still. I’m trying to build up a supply for going back to work and I don’t think it’s going to be possible. Just wondering if anyone else is in the same boat...

Also he has a milk sensitivity and reflux so I’m nervous about trying formula to supplement
