Question to moms with preemies??

So my LO is in the NICU and today they have changed her nasal prongs because the one she had cut her little nose. I am mad, sad for my baby cuz shes getting hurt and now idk if her nose will ever be normal. It looks normal from a straight look but when you look under the tip of her nose it looks like the part that divides both nostrils got dented in or worn down its red and her upper lip is really irritated i couldnt help but cry when i got home. My poor little girl.. my question is if you have gone through this will my baby have a normal nose will the skin grow back im scared of what to expect. Thanks in advance.
