Not really sure where to put this one, because it fits in a few categories.

At one of my antenatal classes the midwife was discussing how labour/contractions are triggered and maintained by oxytocin, which is produced in the pituitary gland.
Then at my breastfeeding class, it was also discussed how oxytocin is also responsible for let down and milk. When i mentioned how i had oversupply with DD, the LC said this is because my pituitary gland must release too much oxytocin and so i create an abundance of milk.

Now it got me thinking, whether there is a link between speed of labour and oversupply/undersupply in breastfeeding?

For me i had a relatively quick labour for a first baby, roughly 5 1/2 hours start to finish with contractions starting at 5 min apart. Then i also had oversupply with breastfeeding.

I’m interested to know if others are the same? Did you have a fast-ish labour and then oversupply or lots of milk? Did you have a slow labour and have undersupply? Or did you have one of each?
