[|Human|] Hi my 9 week old baby girl as a blood blister on her lower lip in the centre, she as had it for about 7/8 weeks. I guess its from being bottle fed, she as the Avent bottles although i have bought a couple of Nuk bottles because the teats are much softer than the Avent, not sure what else it can be caused from or how to make it go away it just looks red and angry, my daughter does not seem bothered by it being there but it just don t look nice. Thanks Tammy
[|AI|]  Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query your baby have symptoms of blood blister on lower lip which seems to be due to poor immunity of body leading to viral infection such as canker sore. Need not worry.  I would suggest you to avoid hot, sharp and spicy food. In case of herpes use antiviral oral and topical therapy like acyclovir are helpful.  Chat Doctor.  Suck on ice pops.
