Laura needs some post-toddler love

"I’ve been reading (and posting) about surviving the toddler twos and threes. I’m in the middle of what feels like hell now, and would love to hear stories about when it ends. Does something miraculous happen at 4? Do toddlers suddenly learn a skill that improves life for everyone for a little while? Is 4 really that much better?

I heard plenty of, “Momma go away!” yesterday. It was a bittersweet Mother’s Day! I could use some encouragement."

Oh, poor Laura. I wasn't able to pay much attention to when the shift happens, because I had a newborn when my older son was going through the transition from 3 to 4 years old. I was just trying to keep my head above water dealing with two at a time. But I do know that my 5-year-old is amazingly easier to deal with now than he was when he was 3. Frankly, he's a delight. And I think msot 5-year-olds are a ton of fun.

Is there anyone out there who has a theory about when, exactly, it gets better (and "when the kid goes off to college" doesn't really count)?
