hey moms, i have a 1 year old who has went through the teething stage already when he's had a fever since Monday. his temperature has came from 100 to 98 since then but he hasn't ate at all. he rejects everything i give him. i don't know what to do. i think he's still teething due to back teeth coming in. i give him Motrin & orajel that has soothed him.
