I would def tell them, as you concider you are co-raising these kids the road goes both ways. Wouldn't you expect to know ahead of time who may be dropping the child off or picking them up, although these people do work for you and have for a while all the kid sknow them and all the parents, I assume. so give the parents some notice on the changes and you should be good to go! It is your business ultimately so you can do whatever you choose, I always remember though: if I want respect, I have to give it first. I just think letting them know ahead of time would be respectful. I concider just the same as changing my hours, or policies. you should always inform parents of ANY changes in advance. Enjoy your kids!!! thats something, alot of people DON'T understand. Just because we stay home to work, we dont have all the time in the world to devote to our kids, sometimes it seems worse than working out of home, we are there with them but cant give them ALL the attention they deserve because the others need it too.
