Sucking/bottle/nursing blisters on lip? Oral thrush

My baby has little blisters on the upper lip. I think it's from the bottle and nursing. Having to do both at the moment to increase babys weight. Is there anything I can do at home to help ?

Also noticing what may be oral thrush ... Any advice on that?

Waiting to hear back from pediatrician but feel so bad for baby :(

Thanks mamas 💖
