I've been wondering whether gestational duration is hereditary - I haven't found a lot of evidence either way, although there is some suggestion that it could be, so I'm turning to anecdote :)
Those of you who have children already- how did the length of your pregnancy compare to your mum's? Or even your MIL's?
secretly hoping it's hereditary on the baby's part instead of mine and he takes after his dad to arrive 10 days early instead of me and ALL my siblings who were 2 weeks late and had to be induced
