This week our bible memory verse is "So in everything, do to others as you would have them do to you.."  Matthew 7:12.   This has helped my kids with arguing.  I really use the bible verses that we learn when they are doing things they shouldn't and most of the time it works very well.  On Tuesday we had just finished reading our bible story and saying our prayers, and I got up to get started on the rest of our school day when my three year old said"Mama how do you get to heaven?".  I was so happy and shocked at the same time that my three year old daughter would ask a question like that.  I just silently said a quick prayer that went something like "God please help me to say the right thing to her right now."  Then I explained it to her in a way I hope she understood.  Sometimes my kids amaze me.
