A movable lump found on an infant's neck may be caused by various factors. Some common and usually harmless conditions include lymph node enlargement, cysts, or lipomas. The lymphatic system in newborns and infants is still developing, so it's not uncommon to feel small, movable lymph nodes in the neck occasionally, especially after a cold or infection.
If the baby shows no other symptoms such as fever, cough, or runny nose, and there is no change in the size, mobility, or consistency of the lump, it may be safe to observe the situation without excessive concern. However, if the lump increases in size, becomes tender, or exhibits other changes, it is advisable to take the baby to the hospital promptly for tests such as a complete blood count (CBC) and ultrasound to determine the underlying cause.
