Daddy Long Legs

Marcus and the kids are still gone, so today Caitlyn and I went to the mall. Amongst other bits and pieces we picked up, I had to get Alannah some new jeans.
I haven't started taking her in to try clothes on yet (when do you start doing that?) but I did measure her the other day. The kids clothes (shirts, dresses, trousers) go by age and list the height, so I checked to see how tall she is. She's 111 cm (we're metric! It's Europe!) tall.
I went to buy her jeans, and size 5 (which I think is for ages 4-5) went up to 110 cm, so I bought size 6. Size 6! The child won't even be 4 1/2 until next month!
It sent me into a panic -- is she too big for her age? Am I feeding her too much? Not getting enough exercise? Will she be picked on at school (she'll already be ne of the oldest, so wll she be absolutely huge compared ot the others)?
Breathe, jane. Calm down. The child is not skin and bone, but she is on the lanky side of normal, not the chubby side. She is in size 6 jeans because she is tall, not overweight. And she is tall because of her 6'1 father (he's English so doesn't believe in metric) who has incredibly long legs.
She's got my eyes, my freckles, my stubborness and my clumsiness, but those legs are from Daddy!
