Pregnant women are treated with neglect during the birth of their child. There is more to clamping the umbilical chord than just clamping . The cord is attached from the baby to the placenta and it contains the blood that belongs to the baby.
In hospitals the obstetrics staff are taught that they have to clamp immediately otherwise the child can lose too much blood. I wondow how all those mammals in the wild don’t bleed to death? I say, if the chord is still pulsating then surely there is still an interchange of fluids happening and you should wait until it stops.
Clamping too early means the baby does not get all the blood that it should get and only gets 2/3rds of the blood which leads to higher rates of aneamia, intercranial brain haemorrages, reduced lung expansion, hole in the heart (congenital heart defect) etc. You only have to wait about 2 or 3 minutes. its not long for the exchange of stem cells, microbes, amniotic fluid, blood, RNA and micro RNA to get into the baby. As the rush of blood changes at birth it shuts the hole in between the heart chambers, which is called the foramen ovale and then the baby can use the lungs instead of the placenta for blood oxygenation.
When you clamp the chord too early the rush of blood is reduced and there is a much higher chance that the foramen ovale is not closed properly and you have a congenital defect, which is really a chord clamp defect. Baby also get assistance with proper gut development from the flow of amniotic fluid and the microbes. In the Whartom jelly and the placenta there are stem cells galore and this is how a baby is grown.
Chord clamping is an incredibly backward practice. It is a stressful event for the baby and early life stressors have an effect on the cells for the rest of the babies life and they shorten the telemere length, which determine how long we all live.
