But He Tiantian presented the perfect version, not some clunky machine, but a pet egg-like device that could be carried around.
Moreover, it required a biological connection with the child's parents, allowing the father (or mother) to feel the baby's movements and experience the various hardships of pregnancy.
However, these hardships were only mental; there was no irreversible harm to the body itself.
He Tiantian intentionally added this feature so that the father or mother could personally experience the entire process of pregnancy, thereby forming a deeper connection with the child.
If it had been left to a cold machine without letting the parents feel anything, they might have become estranged from the child, not cherishing it enough!
Some mothers who found surrogates were so indifferent toward their children, precisely because they had not experienced the entire process of pregnancy.
