Take all the responsibilities as if he is your son.
Always stick to that child as if he were your only one.
Give him all the attention he can possibly need, And also show him all the love and care indeed.
Never neglect that child. Always be his role model.
He's your million dollar baby as also the lotto.
Always picture the best future he can possibly have, And also set the best goals he can possibly grab.
It's a different feeling when they splash the holy water.
I start to set a goal to be the best Godfather.
