Journey it's not necessarily a problem if your little one isn't engaged, my first two never did before birth.
I saw a couple of days ago in ds2's birth report that when I went in at 8 am I was dilated 3 cm, he was still all high!
He was born 5 hours later! It doesn't have to mean anything.
I think on spinningbabies.com there is some advice and exercizes.
