The hospital is usually not keen on this although it does happen for various reasons. There are definately positives to going into labour and then having a c/s (in cases when c/s is inevidable for what every reason) obviously provided no placenta previa etc. Also it might depend on how many c/s you have had in the past. When you go into labour yourself at term the baby is ready to be born. Your reducing the risk of respiratory problems provided bub is healthy at delivery and not compromised from distress from a stressful labour etc. We often see TTN in neonates born via elective c/s as they are done before bub is ready to be born.
Is it possible to have a VBAC?
Also I guess you have to see if the risks outway the benefits. I mean where I work it is not always possible to have a quick emergency c/s as at night or weekend it means calling in a theatre team or if someone else is already on the table been operated on there can be a wait to get them of to get you on if that makes sense. But in some places with 24hr theatres running this is not an issue. I have also been in the position where I have had 2 women needing a c/s and fighting with the O&G who needs it first but I do work where only 1 theatre is running. You will have to decide if you go into labour can you then wait up to a few hours to be preparred and allowing time to do the c/s! I must say where possible I am always a fan of bub choosing when it will arrive. The thing with elective c/s is its expected and you usually predict what will happen. In an emergency its unpredictable and often medical professionals don't like that.
If you go into labour and then have a c/s maybe do your consents now, trim your pubic hair as it gets closer etc so they can just add the date when you do come into labour and little will need to be done to have you preparred. Just a suggestion.
