She has been like that since she was born. I was born with the alcoholic gene. You haven't even begun to explain that away.It is the faulty upbringing that didn't snuff out the tendencies that over time became a child's nature.
If you don't "lay down the law" with that baby now, you will be at the mercy of her temper until you die.
Make her learn now that raging and fuming glean nothing but your ignoring of her.
The allergic reaction to alcohol may be inherited, but the over drinking isn't. (Been there myself)
It is a learned behavior.
I agree that she must learn to turn over he temper to her heavenly father and we are already teaching her that through singing her kids songs about Jesus and showing her videos of gospel music from you tube. It is only through partaking of the divine nature, as Peter says, that we can escape the corruption of this world through lust. She loves those gospel music videos. There are a couple of quartets she really likes. The Living Stones and the Redeemed quartets. She will get so excited to see them that she will bounce up and down in her walker and bounce back and forth from side to side with a huge grin on her face all the time.
