I agree with Lucy, the pushing has alot to do with the breathing. As you push out breathe out, then take a big breath in and repeat. You may be able to get two breaths in in one contraction also. But your midwife and husband will help with that bit as sometimes you forget to take a breath in as your concentrating on pushing.

The crowning is more like a burning. I've been thru it three times and my last time only took 3 pushes and my DS came out. Don't worry instinct will take over and you will know what to do when the time is right.

Good Luck
