Tulip,
I'd guess that if you already know his way of showing support etc, that it will show whilst in labour & although it may not be vocalised, as you will know his ways, it will help you through the pushing etc... does that make sense?

I think just having my Dh there with my drug free labour helped..

I had drugs with my first & had my sis & Mum with me...

I still enjoyed both labours, just differently!!!
