My six year old daughter (who has not yet been baptized) asked me about baptism the other day. I did my best to explain it to her and let her know that I would be glad to baptize her whenever she is ready.
A couple of days later my wife was giving her a bath and she asked my wife if she would baptize her in the bathtub.
Either I did not explain it well or she was not listening well.
I can live with it becase I can think of three things that are more important for her to realize:
1. God loves her
2. Jesus died for her and was resurrected to set her free and give her victory
3. The Holy Spirit is always with her
To me, in her spiritual life those three things are more important than baptism.
