Cows milk is optional not needed
So sorry to hear about your loss ❤️ Milk supply is demand-based, so the more you can encourage your baby to feed on you the more your body will start to produce. You can consider adding in some pumping if you like, but obviously this can be a bit labour intensive!
Try power pumping rather than just a long pump. Mimic cluster feeding with the pump as it’ll help up supply better. Also just try latch baby as often as possible x
Increase latching. The more baby sucks the more you'll make.
