LO is 12 months old and for about 6 months he's had a visible swollen lymph node on the right side of his neck. I know that usually they are no big deal so I just waited until his 6 month well visit to ask the doctor about it. At the time she said we'll just keep an eye on it. At both his 9 and 12 month well visits she still thought it wasn't a problem since it's not getting bigger.

A few days ago I felt another small node in the back of his head and just yesterday felt at least one, maybe 2 more, on the other side of his neck.

He has no signs of infections or a cold but is teething like mad. Could this be the reason for the new swollen nodes? Should I make another appointment with his pediatrician or just wait until the next well visit (in 2 months.)
