my baby is 5 weeks old and just eats non stop during the day. i have been only breastfeeding her since the day she was born but even with her nursing on demand my body just isn’t keening up with the demand. i have a few frozen bags of milk i’ve been bottle feeding her to help but now i’m low on that as well. i really don’t want to go to supplement with formula. any tips or tricks? also, she sleeps 8 hours through the night and i wake up full of milk but it dwindles to nothing by the evening!
