Today is my first day with a new family. They bring their almost 4 year old and 12 month old. I already know this is too much for me. I could take one more child but not two more. I currently have a 2.5 & 18 month old (my kids) a 21 month old and these two. I know after just today that this is too much for me and just don't feel it's fair if I keep them with me. I know my limits and this is it. Do I tell them at pick-up or wait at least till the end of the week? I feel absolutely horrible and have thought about just sticking it out but I know I can't. It's not fair to the others. How would you all handle this?
