Toddlers and little kids

Just came back from a funeral for the uncle or grandfather of two sisters who are friends with my two youngest kids. It is always very sad to see toddlers and and very young children because they really don't know what is going on. They don't know that life ends here on earth. I want to tell them about heaven, and I'm guessing someone has tried to console them. The Lord knows that death hurts really bad. Family and friends were celebrating the life of their loved one. The minister also spoke of celebrating the resurrection because, those in Christ, rise to an eternal life in heaven. The kids need lots of love and compassion to help them grow as a result of deep seated grief...I am sad for them, but I know that Jesus will watch over them.....Rene
