As an adult, having flushed cheeks is often a sign that you might be coming down to something, especially if it is paired with a fever. The same cannot always be said for children. The reason for this is the fact that often when babies as young as only a few months start to have their teeth come in it can lead to a whole slew of symptoms such as rosy cheeks, finger sucking, and gums that are red and sore. It is suggested that if you notice that your baby is teething to give them a teething ring or teething gel to numb the sensation. Speak to your doctor to get their professional opinion. However, if your baby has flushed cheeks in addition to a fever and diarrhea seek medical attention as teething is not to blame.
