Mostly my rule is three doses of meds so in theory if he went to the doctor this morning and has at least two doses today and one in the morning he has met my criteria vice someone who goes to the clinic after work and has meds at bedtime, morning and then needs to stay home to get the third. Issue for me would be the eye drops as I don't do them at daycare so if child needs them in the daytime then they need to be at home. I do meds by mouth as needed. The fact this is Monday means there is a chance the others haven't been exposed to all of the germs so one more day off is in order. I would be ok on the strep because of the three doses of meds - likely will have had 4 with the lunchtime dose. It is the pink eye and if the eye is weeping or draining. What I would be telling the parent is that that is why they would be excluded and if she comes it is my judgement at the door and any amount of glassiness or drainage and he goes home so she might as well save herself the trip and just stay home.
