My 5 week old dd is ebf and has what looks like a little blister in the middle of her top lip. I noticed something similar a week or so ago but only because it must have burst and it left a little flap of dry skin hanging down which I removed. Now looking last night it looks like there is a little blister there. She has recently been fussy when latching over the past couple of days, shes fine once she gets on but she faffs around a bit before. I was wondering if this is normal and if it is possibly hurting her and if it is what can I do to help her? Thanks
