But I think that's pretty common. I see my girls progress in terms of spurts. I saw it happen like that with their developmental progress when they were really little. I absolutely see it now when they are advancing intellectually. It seems if they aren't doing much, then, seem to wake up one morning leaps ahead. I can't remember who or when, but I remember seeing a discussion on a thread some time ago, that proposed the idea that sometimes they are actually working on something else when they don't seem to be progressing in their more obvious or strength area.
It's good to see DD shoot up like that, too. I'll bet she is so thrilled!!!!!!!
