I have a question for the breastfeeding moms out there.

Okay so I'm a stay at home mom with my 1 1/2 year old daughter with baby #2 on the way. My daughter was born with a lip and tongue tie and wouldn't latch. Our breastfeeding journey didn't last long. This time I'm really hoping to do everything I can to breastfeed our little boy. I have already purchased a manual pump and a nipple shield but was wondering if I needed to get an electric pump since I will be home with him 98% of the time. I'm looking at buying the specta s2 but don't wanna spent $200 dollars if I won't need it. Any and all advice to help me be able to successfully breastfeed this time would be great.
