Can a baby get hives from teething? my almost 9 month son gets hives when he is fussing and crying a lot. he is also teething.

It occurs: It occurs probably because of temperature change during crying.

Not from teething: Hives are not caused by teething, but crying can cause hives, but not teething.

Unusual: Hives are not from teething your baby is having an allergic reaction to something he ate or is coming in contact with. Your baby may exhibit a rash on his or her face due to increased saliva production"drooling" during teething.
