There's one blunt way to say this ... 'Don't waste one contraction'.
Too many women waste heaps of contractions and spend hours in labour longer then necessary. The most common cause of delayed labour is getting into positions that ease off contractions because you can't cope with the pain. Or because you can't read whether the contraction is effective. Or because you're tense.
Medically a progressive birth is determined by a narrow perception ... 'approximately 1 cm dilation per hour'. That's nuts really. 30% of women have a progressing labour but don't dilate until the very end. How do they know the labour is progressing? Because the contractions get longer, stronger and closer together.
This means ... and yes it does mean this ... when contractions stay the same for hours the labour is not progressing. Yet most women are permitted to have ineffective contractions for hours and hours because there is an honest belief there's nothing you can do about it. Skills are the solution. Honestly, skilled families are much less likely to let labour linger because they have the skills to work through each contraction, get into positions that are effective, stay open inside the pelvis and cope with the natural occurring pain of each contraction.
When labour is progressing, most women cope because they sense 'things are moving along'. When labour is not progressing women will say 'I just feel the contractions are the same'.
The bottom line of this resource? Become skilled and many of the Pink Kit skills are mentioned in the Powerpoint. Why are these skills so essential? They were developed by hundreds of ordinary families in the early 1970s so you can trust them to be effective.
