Drink water, from a straw held by someone else, between the contractions near the end.
Have a table to lean against which is the perfect hieight to take your weight off the bump during the peaks of early contractions.
Keep monving.
In the early stages of labour, just ignore it. Do whatever you can to distract yourself. Bake or cook something nutritious in between contractions. You'll be glad of it the next day.
Make as much noise as you like but keep it low pitched and open.
Your fanny mimics your mouth SO keep your mouth and lips loose. Check yourself to make sure the mouth isn't tightening.
The contractions at the end of the first stage are a very good time to practise singing opera arias, even if you've never sung one before.
Failing that, moo like a cow.
Have a quick acting energy food available (honey, halva, fruit juice) for when you don't want to waste energey munching away, but you'd like to bring your blood sugar up.
Don't rush it. Your body knows what to do.
Finally, would it be pusing it to say 'enjoy it'?
