Well I get your points,
And my son has been with her since he was 14 months old...She has taught him words, how to pick up after himself, she even did some of his laundry when our machine was broken...Honestly he didn't know how to use a spoon or drink out of a glass and now he does all that....
He asks for her and says he "lubs" her..makes me jelous -sorry bad spelling- but happy...I just can't always say I would have the cash to pay....thats my only worry.
