my little brother ate a hot fry

so my bf was messing with my little brother and acting like he was gonna give him a hot fry and then he’d pull it back. well, my little brother broke the fry and shoved it in his mouth. i grabbed him and tried sticking my finger in his mouth to get it out and when i did i couldn’t feel anything. he kinda made a face and then took a drink from his cup but didn’t act like it bothered him. he’s about to be one. should i be worried? please no mean words, we was just teasing him.😩
