Just have to say - whenever someone else watches the twins, which is none too often, they invariably end up frazzled, a little frantic, and exhausted. Even if that someone is around them on a daily basis. Even if its only for an hour. I'm pretty sure this is why children need a full time mom, someone who knows that sometimes a little Curious George can go a long way, that the girls will do almost anything if there's a promise of chocolate or marshmallows in the end,* and knows all the signs preceding a meltdown. I know its terrible, but I do feel gratified when someone else takes the reigns and sees how formidable raising twin hooligans can be. Everybody needs a bit of validation now and then.
*So will I, for that matter!
