Palpable lymph node in 3 month old?

Alexis • 💙Brantley Paul👶🏻

I've noticed there's a palpable lymph node (maybe the size of a bean) in my 3 month old. It's located where the base of the skull and the neck meet. When I touch it, it isn't soft but it does move. Is this normal?

He does have a clogged duct that gets infected every now and then so I don't know if that's associated with it. But, should I be worried?
