I agree with the baptism by immersion. There is just too much information in the Bible to do anything else, for Christ was only baptized in this manner as an example of how we should do it.
I also believe that children are innocent in the eyes of the Lord and should not be baptized until they reach the age of accountiblity where they have a better understanding. This the passage where I get my information.

I do think it is wonderful for you and your husband to have the desire to introduce Christ into your child's life.
Instead of baptizing of infants in my church, we give them blessings and they are very special.
