Congrats to Mariah Carey & Nick Cannon......Bring on the Babies....

How many people thought Mariah Carey and Nick Canon would make it to see 4 years of marriage? I am happy they are doing well and congrats to them on the new babies. Some people are speculating that they used fertility treatments to conceive. My husband and I are trying to have a baby within the next year. What is the best way to do this without any treatments?
