Just wanted to give you a big warm , what a time for you to have to think about so late into your pregnancy

I hope someone can come in and give you the stats, but as things went well with your first bubba, you would still be a low risk for it happening this time, you may not even need the assitance as bub may be in a different position and your body has done it before so it will have stretch more IYKWIM.

I hope that someone can reassure you and your DH, 60km is a big drive, but hopefully it wouldn't be necessary.
Take care and all the very best for your upcoming delivery xxoo
