I've just recently given birth and little one is lazy to latch but also have flat nipple - midwifes been so helpful and people who trained with breastfeeding. I've been expressing my milk and it's slowly coming. However I've been experiencing shivering- I go cold and then endless shivers. I know it's not an infection as I'm on antibiotics as I had surgery. Just wondering if anyone else had these and when will it stop?
