How are the couples been prepared for delayed cord clamping

In Happy Mom Pregnancy/childbirth classes been prepared for delayed cord clamping.
But not everyone were able to establish delayed cord clamping.
Delayed cord clamping is at least 2-3 minutes delay in clamping.
Unfortunately there are many reasons , listed some to my experience
Due to delivery process like
Cord around the neck: baby been rushed to the Neonatal Intensive Care Unit
Baby passed Stools/ Meconium
Forceps/Vaccum Delivery
Delay in baby cry
Fundal pressure / pressure given over the mother stomach to expel the baby
Episiotomy; mother would be bleeding no time to wait

Than how can to have Delayed Cord clamping to happen
If there is a Natural birth/water birth is happening , delayed cord clamping is more possible
Like no fundal pressure, no episiotomy, no rush to deliver the baby ie no push push while delivering its a natural expulsive reflex were it will happens on its own.

Medical emergencies like meconium stain,baby didn't cry than delayed cord clamping is delayed.

All this requires prior preparation for the couples to decide according to the circumstances.
