My son is sick today

He was throwing up last night, got sniffles and cough. He didn't sleep well last night and niether is daddy.. So my son is at home today resting hope he feels better soon so he could go back to school. I thought he has pink eyes but I guess not. I think it's just an eye allergy. His eyes is not red today so I think he is better I just let him stays home so he can rest for not sleeping well last night..
