Question:

I noticed a lump about 2cm in size on my baby's neck. Is it normal for babies to have these kinds of lumps on their necks?
Answer:
I understand you must be worried after feeling a 2cm lump on your baby's neck.
It is actually quite common to feel small lumps (lymph nodes) on a baby's neck. They frequently become palpable during or after a cold or a mild infection.
Characteristics of Normal Lymph Nodes:
• Size is 1cm or smaller
• Soft and easily movable under the skin
• Painless
• Often felt symmetrically on both sides
When to Seek Medical Attention:
• The lump is 2cm or larger (which applies to your baby's current situation)
• It feels hard and does not move when touched
• The overlying skin is red and the lump seems painful
• It continues to grow over a period of 2 weeks or more
• It is accompanied by a fever or weight loss
Because a 2cm lump is larger than what is typically considered normal, it is highly recommended that you take your baby to see a pediatrician for a thorough check-up. While the vast majority of these lumps are benign (harmless), a proper in-person medical evaluation is necessary to determine the exact cause.
