Sore on Lips 😩

I woke up this morning with a sore on my lip. Idk if it’s contagious but I keep catching myself kissing my 2month old 😩😩😩

He had his check up today too and I forgot to ask the doctor about it

UPDATE: my lips never break out or show a sore (no scabs Nothing) it’s just a little tingle I get on my lips

I have not once’s kissed my LO on the mouth. He is my first and I just haven’t kissed his mouth. I kiss like his cheeks or head and I’m trying to remember the last time I kissed his hands cuz if he tried putting his hands in his mouth worry me now too
