Milk supply needs work.

Hello guys, close to 4 weeks since I had my daughter via C-section. She has always had issues latching on so I have pumped but I feel like I haven’t been able to pump a ton per session.

I find it difficult to pump during the day, and was looking at a wireless version. Is it too late to build back up supply?

I have the Luna Montif double electric pump. I’m looking at getting the Elvie or the Willow but not sure which one to go with. Any thoughts on tips to build up supply?

Still; waiting on appt with LC But was curious if any of you mamas have had a similar issue.
