dont GIVE UP!!! NEVER EVER!!!! must have these in your mind at all times!!!!
I experienced these too for 2 kids!!! but still bfed them successfully in the end!!
1st - r you taking any milk formula yourself??? Anmmun is a must hav!!!
2nd - continue to let your baby latch when she's hungry for at least 15 mins each side [if she's still hungry, feed her formula after that]
3rd - must continue to express whether got 1 drop or didn't [which pump r you using? Avent manual & medela electric r recommended BUT choose only one] you must understands that the stimulation from baby sucking & pumps r different & can confuse your breasts!! if your baby is drinking, continue to let her latch often cos they may b drinking but you dont realise it.
Be positive, r you alone at home? If moral support is not there, then you must be very +ve! dont let the -ve remarks affect you!!!
