Hi..my lo is a total breastfed baby since birth. she has at least 6 wet diapers a day but her weight gain is very slow. currently 17 weeks and weighing only 5.3kg. I don't feel any pain at all during and after breastfeeding but I notice that my nipple misshapen. I tried making my lo open mouth bigger to achieve deeper latch but it my nipple still ends up misshapen. Is my lo not getting enough milk thus the slow weight gain? it also doesn't help that she's a very active baby.
