Advice on how to navigate wfh and baby

Hi all! I’m a FTM and I’ll be going back to work in February. I EBF but I started pumping and having my husband give our baby a bottle so he gets used to it. I WFM with only one day in office a week. My manager is awesome and is allowing me to stay home for the first month while I figure out a groove. I’ve always gone to my parents house to work vs my small apartment. My mom is newly retired and will be watching my son while I work. I’m not sure how that will work but I’m hoping for positive results. My question is … do you pump and allow the caretaker (my mom here) to bottle feed the baby or do you take a break and nurse the baby? Will it cause confusion or distress to myself or the baby if we’re constantly back and forth during the day? And advice is appreciated.
