I have looked into this a little bit and decided to do delayed clamping (ie no donation will be possible) for a number of reasons.

My understanding is that it is good to let a newborn get the blood from the cord as they get the benefits from the oxygen while their little lungs get used to working for the first time. Nature seems to have designed it this way to take the pressure off the lungs.

Allowing the blood to flow also benefits you as there is less blood left in the placenta - making it easier for the uterus to expel it and less chance of hemorrhage.

I read somewhere - can't remember now sorry - that babies seem to have an inbuilt system for getting the blood they need from the placenta/cord after birth. If they need more blood they tend to cry more and cause more blood flow, if they need less, they tend to be calmer. I think that sounds pretty cool, pretty clever and I have faith in a great natural system like that.

So for me, all things considered I am not keen for an early clamp.

I am sure some people do have good reasons for a quick clamp and/or storage of cord blood, everyone has to work out what is best for them. I just wish there was more information out there and that the hospitals themselves were more informed!
