Have you been to antenatal classes? DH & I attended them together & it was really great for both of us in terms of learning what to expect.

For my DS's birth, DH was wonderful. He did everything I asked, when I asked - held the shower nozzle in the right place, held my hand, got me drinks regularly as I didn't think of it myself so he just did it. He talked me through the contractions helping me breathe when I started to panic. He got the midwife to come when I asked. He didn't want to "catch" the baby but he did cut the cord.

For DD's birth, she came so quick, his only job was driving me to the hospital then the midwives took over. Be prepared that something like that may happen too and just be there.

Make mental notes during the birth so you can tell her afterwards what happened as there's a good chance she'll forget.

Support her birth choices as much as possible & be encouraging. I would say you would do that anyway given that you've taken the time to ask advice.

Congrats & good luck
