I agree about the drop-off pick-up...I hate going to pick up my son midday as I have been this year (he is in morning preschool at the school he'll be attending next year). Next year he will be taking the school bus, which will drop him quite close, so I don't have to get everyone bundled into the car at least. However, as I will be doing it for him, it won't make a difference if I do it for another. However, Playfelt has raised some good points. I am imagining the chaos of two rambunctious 4 year olds with the 5 little ones ranging from 18 months to 3 years. In good weather it will be fine as we spend most of our day outside, but in winter I'm not sure. And it's true that my son may want to go and have down time in his room...especially since he won't be napping anymore (now he is still napping, so this may be a bit of a hard adjustment). I can't take a one year old right now because I already have three 12 month olds and also I cannot fit another child in the car to pick up my son. September or summer is what I am aiming for. The family I have coming for an interview this weekend has a child who will be 15 months in September...at least she should be walking.
