My elder son received alot of money as a gift when he was a baby while the second one didn't receive as much. I was thinking of converting their cash to gold.

We will not inform them of this when they are older.

Q: Should a parent be equal to all of their children in terms of finance and gifts?

Question: Will it be fair if the father sets up no. 4 in the business, without paying back. Basically giving him a business and not giving any other brother the same.
