Lip tie?

Sa

I’m gonna double check with the doctor at my daughter’s 4 month appointment but thought maybe you guys could give some insight. My daughter was really hard to nurse. She was a lazy feeder and would fall asleep no matter what we did. We checked if she had a tongue tie and the doctor and LC said no. Now I’m noticing that she is a super messy eater still even with her bottles. The nipple flow isn’t too fast and is we use a slower one she gets MAD. I’m wondering if she has a slight lip tie. I had to give up BF because she would get upset and wouldn’t latch even with a breast shield. Broke my heart. Any insight would be super helpful!

This is how she looks with the bottle

Bottom lip curled down and top lip never curls up.
