10 month old sick and won’t take solids

Isaura

He has been nursing without issues and has not had a fever last 2 days but refuses to eat any solids except for puffs. He is on antibiotics and with just nursing and nothing more substancial in his tummy, he is very runny and it is burning his poor tushy. Other than snotty and a cough of the drainage of his sinus to his throat, he doesn’t act sick while awake. Has been 4 days of no solids or baby food.

First time that he has refused some food when sick. Don’t want to keep depending on puffs but no fruit or veggie he has taken, mostly he played with it and tossed it to the floor. Anyone gone through something similar and after a while lo went back to eating normal? I’m hoping he is not going through some picky phase that won’t turn back. He was a good table food eater.
