Not wanting to lose control of the labour if medical intervention is needed
Many partners feel they need to take on the role of negotiator if things do not go to plan and intervention is required. This can be a disempowering experience because you are generally relying on the information and recommendations of your professional caregivers. Most partners instinctively want to protect the woman in labour and feel distressed if things move out of the boundary where they are able to do this.
Become informed. Knowledge is a powerful tool to help you. Keep an open mind, be flexible to changes that may happen along the way. Work with what is happening in the labour, by understanding the process of labour. Always ask for the reasons behind suggesting medical intervention. What are the advantages and disadvantages for mother and baby and are there any other alternatives? Once you have this information discuss it with your partner, in private if possible, so you can make your own decisions.
If the labour has turned into an emergency situation then you generally won't have an opportunity to negotiate your options with your caregivers. They will need to act quickly and may not be able to attend to your needs, while they work on your partner and/or your baby. You will need to trust their actions and judgements. Try to be calm and stay as close to your partner and baby as possible. Ask for a debriefing session when time allows and things have settled down if you need to. This may not be appropriate until the next day or so.
Hoping I will know enough to support her through the labour
Partners often ask, "Will I remember everything?" While having information will play a big part in supporting her, 'being there' is probably the most important and sometimes the only task required, especially if your partner is a very independent labouring woman.
You know your partner better than anyone.
