Dian tang, I rem u said abt buying 0-3months carter from gmarket. The size is v small, my girl is wearing 6-9months bought from qoo10. N wearing 3 months carter bought from USA. N she's now abt 2 months old. So I think u better buy bigger size to stand by.
Chevy, maybe u should try feeding her in smaller amt n more frequently. Hope this helps.
Adeline, do prenatal yoga as its can help with our body ache.
Koirc, maybe u should try to latch on again. If bb chew or suckle for comfort, normally I would say no to her and she's seem to understand it. Haha. But u have to make sure that the latch is correct or else will feel nipple pain again.
