1. The most powerful argument against surrogacy is the fact that baby and mother's brains are biochemically linked.

Throughout pregnancy, their brains interact through the secretion of hormones.

2. Even the slightest drop in mother's blood sugar levels stimulates the baby's stress axis.

When the baby accounts for around 15% of the mother's metabolism – its blood sugar levels plummet.

It then senses that it can no longer be supported.

3. The birth process itself is a result of the relay of oxytocin between baby and mother.

There is a very real reason children generally feel more instinctual affinity towards their mothers than they do their fathers – and it is precisely a result of a 9-month neuro-symbiosis.

4. To separate mother and baby at birth? – it cannot be done without negative implications for the psychological growth of the child – and the mother.

To advocate for surrogacy because one feels it is one's due to have a child? – Narcissism.

Solution? – Adopt.
