Hi mummy. I'm same like you. My right nipple is shorter than the left but I still latch my baby on that side to prevent it from clogging even when I pumped out the milk. Your baby should not need to turn his/her head towards your nipple. Make sure your baby's stomach and yours are at the same level then put your nipple in between baby's nose and his/her upper lip. Your baby will auto suck your nipple like that and it won't be painful. Get yourself a nipple cream. Helps to soothe the pain.
