I've struggled with bf since dd2 was a couple of days old. I had sore nipples very quickly which became very badly cracked after about a week. Everyone checked her latch and declared it to be fine. I had mastitis twice but persevered... Dd2 is now 18wks. About 2 weeks ago the cracks had gradually healed and were no longer painful. Then i started to get sore again and today I noticed that the cracks are opening up again. Dd2 is teething, the first tooth is just cutting through now, and dd2 isn't latching on well - she won't open her mouth wide and turns her face downwards when feeding. She wants short feeds all the time, including 4 in the night when she was previously sleeping through. I know this is probably the 4 month sleep regression together with teething, just wondered if anyone had any advice? I was so chuffed that things seemed better a few weeks ago but now it feels like we are back to square one.
