I feel a few pea sized lumps under my 9 month old's chin. Its not visible to the eye but it can be felt. I first noticed it when he was around 2 months. I asked the pediatrician about it and he said he wasn't alarmed by it but he'd keep an eye on it. I guess over time I kind of forgot about it but he is now 9 months and it's still the same. I know they are lymph nodes but i cant determine if it is swollen or if it's just normal size. Has anyone experienced this? He has a doctor's appointment Thursday and i will ask about it again then. I'm trying not to get too worked up over it but i cant help but to worry. He has severe eczema as well, don't know if it's related or not but worth mentioning.
