WOW ok i am also a child care provider and I have to say I disagree with Amanda, firstly I change the children if they spit up on themselves at all, to me it's just the normal course of things i keep several spare outfits on hand for the little ones i keep. So basically if your son seems fine even though he did throw up, i would guess that it was the same way while he was at daycare, and it isn't as though they didn't tell you it happened. they jsu used some basic disgression i regards to weather or not he was really ill enough to bother you at work. By all means if this bothers you talk to them, but had they called and told you that yes he spit up in their words but he was behaving perfectly normally and didn't seem to actually be ill, would you have rushed to go get him or trusted that should he actually be sick they would call you back? I've had this happen with my own kids at school,and yes the school always calls but normally if the kids are ok i don't bother to go get them unless the school asks that i do, the school is smart enough to know if the child should be there or be sent home but they have to notify the parents, unlike school though the daycare sees you every day and can notify you of things at pick up ect. I hope this makes some sence, but by all means talk to them if you really have a concern and see what they say, chances are he was fine and they didn't therefor think it was something that couldn't wait, but if you would like them to be quicker to call you then let them know that. good luck
