SJ, I'm not too sure about the 5/5 with arrow pointing up - I did read somewhere about being a number of "fifths" engaged, I might try and google it again for you...

BUT! I asked my Obs yesterday if I were engaged and she got a bit funny about it - she said that the term "engaged" is bandied about too much these days and the only real way to tell how far down the baby has moved is to do an internal exam (which as you know she didn't want to do).

She said being engaged to her means that the head is down and cannot be turned, rotated, by palpating the baby. So she can't turn my baby any more so it is engaged. I don't have an orange book or anything so I am not sure about the arrow etc!

HTH!
