Using Haakaa milk collector while breastfeeding on another side

This is how it will work when the let down occur while u breastfeeding in the other side. I manage to feed baby on one side only when my supply gets more on 1 months plus. It’s really good because I get to keep some milk during feeding hours. Pumping between the latch on feeding session is just too tiring. The milk collector is easy to clean too!
