DH hadn't gone to any classes beforehand, nor had he done any reading (I'd even bought a book from a male perspective, but that was also ignored). He just didn't see the need.
He was very quiet in the hospital. He was very "present", but a bit lost as to what to do or how to help. I ended up being sick a couple of times, and he grabbed bowls, got a damp cloth for my brow, ...
Then I ended up having a shower for about 2 hours (one long one, back onto ward, but then retreating into shower again). I just sorta spaced out and wanted to concentrate on being quiet and letting it happen, in quite dim lights. DH seemed to understand that without needing explanations, so he sat on the hard chair in the bathroom, minding my towel and prepared to pass things if needed. But mostly sitting there and letting me get on with it (and he had nothing to read or do). We occasionally had a little chat.
When it came to pushing etc, he didn't know what to do to help. And I couldn't explain at that stage. So he couldn't hold up my leg that the MW wanted up in between contractions and as I couldn't keep it up anymore myself on my side, MW made me go onto my back lying down (last place I had wanted to be). He just wasn't able to be my advocate. But he did get so excited when he found a facecloth in the bag and wetted it to mop my head (he thought I had it for later washing - didn't realise that was the original intention when I packed). And he was very encouraging talking to me when we were talking and during pushing (and he DID realise to shut up a lot). And he DIDN'T tell me that there were loads of concerned faces about the room (DD was getting into distress and not coming out - but she came out under her and my own steam just before the main posse arrived in), just kept up the positive encouragement.
And he was so proud of me afterwards!! That was great. I think he'd thought it would be "just like the movies", and not that painful.
We've pretty much decided to stick with 1, but if there was another, I think he'd be a much better advocate next time. But even just as a quiet supportive presence he was great for me, and he kept it all positive rather than bringing any negatives or fear into it.
