i have a sore on my right breast due to DD's sharpe tooth rubbing when feeding and oh my it hurts! she only has one upper through with 3 more onthe way and im dreading them already, apart from making sure our attachment is ok (i have been making sure she has a wide open mouth before attaching) what else can i do?? shes not biting (yet) its just sitting on the same spot and aggrevating it each feed. i do have some lansinol (sp) but its out of date, should i bother putting anything on it or just leave it?? im worried it may get infected
