What is it about wanting whatever the other person has even though what you have is precisely the same but for maybe one minor variation? We want what we cannot have, only to find out that when we get what we want it wasn't all it was cracked up to be. The greatest satisfaction comes from merely having it, knowing that the other person does not. That's ugly.
The other evening I was giving the girls their routine tubby and decided to momentarily step out of the bathroom to grab something. No sooner had I left the room when I heard the girls screaming in unquestionable frustration. I hurried back into the bathroom to find them bickering over a washcloth. Poppy had a blue one and Willow had a white one; but Poppy wanted the white one even though they were both the same size, shape, age, softness, etc... Willow seemed to have a glean in her eye as she peered over at Poppy knowing she had something Poppy wanted. (I don't remember getting that worked up over washcloths when I was their age, although I do remember taking joy in having something my siblings wanted.) Rather than try to reason with the girls I quickly opened the cupboard drawer and found another identical white washcloth to the one Willow had. I then handed it to Poppy. All was now well in the world as they both possessed a piece of white, wet fabric they could hold up to their bodies. I then made them put the washcloths down, look at each other, tell one another they were sorry for getting angry, hug and then kiss. Seeing those two little naked bodies hold one another and whisper into each other's ears was a pretty sweet sight.

Victoria and I are trying to teach the girls what's ours is yours and what's yours is ours. It's hard when Poppy thinks that almost everything is hers, even when it was originally given to Willow. The easy thing to do is just buy two of everything. For example they both each have a little red tricycle, but one has a basket on it and the other doesn't. Of course, guess which one they both want? One thing that's impossible to buy two of is mommies and daddies, especially mommies. There's a real nasty "jealous bug" (that's what we call it in our household) that comes out of its cocoon every time one of the girls receives attention from Momma and the other doesn't. It's especially active in the early morning right after everyone wakes up from a long night's sleep and wants a snuggle. I don't know how Victoria does it, but she manages to spread herself in ways that eventually satisfies both girls.
Lot's of patience, lots of discipline, lots of forbearance, lots of training, and lots of love go a long way. The hard part is that it takes so stinking long to get there. That's where vision comes into play. If we cannot keep our eye on the long of the short of it, we're doomed. The immediacy of the here and now is not where the reward lies (although sometimes it peaks its head up every once in awhile for us to see).
Quite frankly, I'm with Poppy and prefer the white washcloth too because when I look at it and see how dirty it is, it's a reminder just how deep the stains are and just how much of the filth has been removed.
Scrubbing Away,
