My newborn (26 days) has oral thrush. I have to apply a gel in her mouth with my finger. I did this today and she started suckling my finger, which took me by surprise. She sucked my finger up to the roof of her mouth and my nail dug right into it, possibly breaking the skin, I don't know. She started screaming and wouldn't stop, and I feel absolutely awful. She wouldn't settle with me so my mother in law took her and she settled with her, making me feel even worse about myself. Now I am panicking that my nail broke the skin and she will get an infection and die because of me and my stupidity. I just didn't expect it. I don't even have long nails. I just feel so inadequate and panicky now.
