Small mouth causing latch issues

My baby is 3.5 weeks old and we’ve had a lot of issues latching (which is super disappointing considering I wanted to EBF really bad!). We had his latch looked at by a lactation consultant at his newborn appointment and she said his mouth has a unique anatomy. Basically it’s just really small plus a lip tie, short tongue, and receded chin. This has caused nipple cracking and areola bruising from him gumming rather than properly sucking the nipple far enough into his mouth. I’ve been exclusively pumping and bottle feeding, which has being going well, but is not an ideal long term solution for me.

I had a follow up lactation appointment this week. We tried a nipple shield for a few minutes, but he was getting frustrated since he hadn’t eaten in a few hours and it still didn’t feel great. The lactation consultant suggested I continue with pumping and bottle feeding, but didn’t do much in the way of making me feel like the latch would ever work. She said I could try again in a few weeks, but I’m concerned he’ll continue to get frustrated at the breast if he gets too used to the instant gratification of a bottle.

I can’t be the first mama to face these issues! I think I may order a nipple shield and try again on my own in the comfort of my own home. I know some pain is normal, but I’m wondering if any mamas have toughed out a gummy baby and had long term success breastfeeding. Any feedback or similar experiences would be super helpful. Thanks in advance!
