In a word, no. New mom and statistics geek spacefem is gathering and displaying data about gestation length and found that it varies widely depending on a host of factors. The "40 weeks" gestation used as a benchmark is the average and median for term births, but only 5.6% of spontaneous births happened on the predicted due date. The upshot is that you don't have to be "average" to be "normal". Spacefem also has graphs on the probability of induction by gestation date, birth weight by gestation date, and more. And you are invited to add your data to the ongoing survey as well! Link -via Metafilter

Here's a sled your kids can use whether there is snow and ice out or not! The secret is that the sled itself has ice on the bottom. There are two ice molds that you fill with water and set in your freezer. When the ice is solid, attach the molds to the underside of the sled. Clever! Of course, a parent should determine where this will be used. Link

Photographer Phillip Toledano (featured previously) speaks honestly about his new baby girl and the feelings he had as a new father. It was a rough start, as many fathers know.

Some men deal with their baby rage by drinking or playing video games.

I made plates.

I thought it was high comedy, but Carla was not so amused.

For the longest time, when people asked me to see a photo of Loulou, this is what I'd show them.

I liked not showing the usual cherubic photo. An adorable shot of Loulou poking her head out of a casserole pot, or something similarly bilious.

Does ever baby picture have to be sweet and beautiful?

Things changed as time progressed. Enjoy this photo essay by clicking the pictures or text to advance. Link -via Metafilter
