If only one parent is Christian. Paul says in 1 Corinthians 7:14, that the children of Christians are clean[/QUOTE)
Hi Lon
The Bible says you must be born again.
I believe all children go to Heaven if they die; but there comes an age of accountability; like when in the times of Moses, those above a certain age were held accountable and did not enter the promised Land.
Having Christian parents will not get you into Heaven; only believing on the Lord Jesus Christ, trusting in His precious blood, and knowing Him will get you in, because He said, "I am the way, the truth and the life, no-one comes to the Father except by me."
Seek Him while it is still today, for we do not know when He will return for those who love Him. For those who do not, there is the Judgement and an eternity in Hell, because they rejected the very Son of God who loved them and gave Himself to suffer and die for their sakes.
I hope I have been a help to you and that one day I see you in Heaven.
Kind regards
Butterfly
