I started out with school age, as long as they were in or starting school that year I'd take them. I didnt want to deal with diapers, naps, strollers, high chairs, babygates, or potty training, bascially, I wanted kids my own kids ages. Then I realized I needed to have at least 2 of my spots filled by full time (for the income) so I resigned to give up pretty sweet deal and set out to look for 2 years +, but ended up with a 3 yo and a 9m old. Which I'd do again, but not for a while, I have my 3rd child due in Jan, so until this one is about 2ish I'd likely not take any kids any younger than it, just for my own sanity!! LOL! I love babies, but only 1 at a time!
