i think it would be really cute!!!! i can imagine him checking up on them, trying to make them smile, showing them videos that make them laugh, share cute animal pictures~~ i can see him being the type of person to be by their side, insisting to hold their hand(“don’t hold my hand, you might get sick t-“ “i don’t care!!! i want to be there for you!!!”), he would bring them water or tea when needed, also soup or something to eat~ he would bring them a stuffed animal(or many~~), he may stroke their hair every now and then!!!!!! i just imagine him being very gentle and caring and patient to them!!!!!
