Breast Pump

Firstly, what are your best breast pump suggestions for maximum milk withdrawal? Secondly, I currently have 2 1/2 yr old boy and am due with my little girl at the end of November. I exclusively pumped with my first but now am trying to decide what to do with this one as I won't have as much time to dedicate to pumping for the 30 min and then feeding and then cleaning parts; whilst taking care of/not neglecting my toddler. Also sleep is important and we all know how little we already get with a newborn needing to be fed every two hours. The issue of course of me breastfeeding is my partner can't help with that lol but I feel like it might not require as much dedicated time as pumping exclusively. Any suggestions from moms who have been or are in a similar situation?
