Teething?

Freya • OB RN- 👼👼💙

My son is 4 1/2 months and has been miserable when he wakes up and goes to sleep, and biting pretty much everything that comes near him. His gums are swollen and I can see white underneath so maybe that’s teeth lol. But the weird part is there’s bright red veins on his bottom gum line where his teeth would be coming in. Just wondering if it’s actually teething.
