I have a friend who is very tall and they told her that her all her babies would be small. The last one they told her was measuring 3 weeks behind dates. He was born at 39 weeks weighing 5kg and was 57cm long. Fundal height is only a guide, tall women often carry smaller than shorter women. Try not to stress. If all your other scans and measurements have been fine, this one most likely will as well. Also remember that ultrasounds are not terribly effective in calculating weight though most Obs swear by them.

As far as breech - DD2 was a footling breech and I read all the research too. I ended up with a CS and as much as people are always saying you can naturally birth a breech baby, you have to be comfortable with it. You have to know the risks and weigh it up for yourself. Just because other people think that it is possible (and constantly remind me that I did not need a CS), it is not their baby they are risking. It is yours so you have to be comfortable with your own decision. I felt the same way that you do - if there were people who were at all qualified in dealing with breech babies, I would have thought about risking it, but no-one where I birthed seemed to know anything except to be scared of them. I really had very few options and once I went into labour, the decision was made for me because it was hospital policy not to have footling breeches naturally (risk of cord prolapse). If the baby was a Frank breech or complete breech, they would have tried turning her or let me have a go birthing naturally but due to being feet first instead of bum first it creates further risk.

I read all the research too and at the end decided that yes, some women have safely birthed footling breech babies, but some have not. Contrary to popular belief it is not always that they weren't being cared for properly by people who know what they were doing. It just wasn't a risk I was happy to take. I was not thrilled about having a c/section at all either and I still have lots of disappointment about it but I am very thankful for my healthy baby girl.

Don't know if my ramblings helped at all but do what you are comfortable doing and no matter what anyone else says ... do what you think is right.

Good luck. I hope your baby turns for you
