Large nipple moms i need your help!

My LO is 10 days today and we have been having issues with my latch. I have the biggest nipples known to mankind and now after weighing baby I know he isn't getting enough. My nipples arent as sore as in the beginning, and the bloody nipples have all but gone away, but i will still get a white ridge on my nipple. it doesn't hurt though and i'm not sure if its just me getting used to it. Baby was weighed today and hasn't gained his birthweight back yet 😔in fact hes only gained 2 oz since he was last weighed at his pediatricians office on 1/16. Anyone else have this issue or tips? My WIC appt isn't until the 29th to see if I can get help from their breastfeeding counselor 😣 We also now have these really yellow/orange pee diapers that i took him to urgent care and of course those Dr.s are pretty useless since the town i live in isnt very savvy when it comes to babies 😑 so waiting til monday to call the pediatric office
