Why are the bottom of your babies feet bright red and hot to the touch sometimes?

Bright red and hot feet in babies can be a normal response to temperature regulation, as their bodies are still adjusting to the external environment. It may also indicate increased blood flow due to activity or excitement. However, if the redness and warmth persist or are accompanied by other symptoms, it could be a sign of an infection or other underlying issue, and it's advisable to consult a pediatrician.
