Baby’s gums

Marcy

So my LO is 3 and a half moths old and he started teething around 3 months. I can see his two front bottom teeth through the skin but today I noticed his gum is really red where his bottom incisor should be and it looks like there may be a little bit of a bump. Is this something I should be concerned about? Shouldn’t it be a while until he would get his incisors?
