I don't know if the use of so, it is possible here!
"we cant not protect our children from everything. So some plans won't make their way in their life."
I found this on the Internet :
- In formal contexts we can use so instead of an adjective phrase after a verb:
The bus service was very unreliable when I was young and it remains so even today. (It remains very unreliable …)
- We use so as a subordinating conjunction to introduce clauses of result or decision:
I got here late. It was a long journey, so I’m really tired now.
