Hello fellow mommies!!

My daughter is four so I’m pretty much clueless when it comes to all this pregnancy and delivery and after stuff again. Lol. I breastfed her until she was 16 months and I plan on BF my second (currently 16 weeks) as well but I will have to pump some as well because of work. Do you have any tips on how to produce enough? I never really could pump over 1 oz with her, but I definitely had enough to produce from the breast naturally. I never really cared to bottle feed so I never knew any different.. thanks!!
