I have flat nipples and was given a plastic nipple to attach over my nipple- It works sometimes but if my baby is really hungry he just fusses and pulls the nipple guard off my nipple its like he is panicking. When he finally does latch on after feeding my nipple is so sore i can barely put my bra back on. So lately i have just been pumping and feeling him my breast milk from a bottle. Is this horrible? Any ideas that can help me out?
