A couple of months ago my son began to ask if he could have a boy baby. I told him he could pray and ask Heavenly Father to send him a boy baby. He ran towards his room and was there for a little while. He came back to tell me, "I prayed and asked Heavenly Father for a boy baby, Mommy."
After I found out I was pregnant again, I told him about it, and he said, "Is it a boy baby? I prayed and asked Heavenly Father for a boy baby." I let him know it is too soon to know if it's a boy or a girl. I must admit I am worried if it is not a boy, but either way boy or not, it will be a good lesson in prayer.
