Help! Sick baby won’t drink

Mystic_Gemini • single mother by choice to an amazing little boy - 12/22/17

My son (almost 10 months) has an ear infection with a fever around 101. He’s been on amoxicillin since yesterday plus tylenol for fever/pain. Yesterday he only drank 2 of his usual 4 bottles of formula. This morning he completely refused his first bottle. He did eat some fruit purée but I’m really worried about dehydration especially with the fever.

Any advice?
