First time mama over here and have questions!!

My baby isn’t here yet but I plan on breastfeeding and this question I’ve just pondering forever now. I plan to also have my boyfriend give her bottles so they can have bonding time also. So of course I’ll have to pump when I leave her with her aunt or uncle and when I want my boyfriend to feed her, but is there a good ratio to how often you pump and nurse? I want to do as much nursing as possible, but I’m just curious if I will also have to pump as much. The woman my sister in law nanny’s for pumps quite a few times a day. I believe she told me she wakes up around 3 to pump and then pumps when she gets off work. So I was just kinda curious if there is a ratio.
