My baby is 5 days old and I just can't get her to latch deeply. I am so sore! She wants to feed and gets very impatient. When I have had someone's help, it's better but by myself, j just can't do it. I know my milk is there as I can put 3oz in 15 mins. I gave up at 3am and fed her expressed milk from the bottle and now I feel like such a failure. I had to pump before for my first as she was prem and really don't want to do it again but also can't cope with the screaming baby, exhaustion and pain! Best tips?
