I can't be the only one who can't get baby latched correctly.

We are 10 days old now and mommy's nipples are still hurting! I can't seem to get him to flange his lips or stick his tongue over his bottom gums or latch deep enough! I've tried everything! Any tips? I couldn't have a lactation consultant when I delivered because it was late Friday night, and no consultant on the weekends 🙃 I don't have the means to pay for one either, so what else can you recommend? 😭

Side note: he is gaining weight. We went to the pediatrician for a weight check this morning and he's gained 4oz.
