Good i was fixing to say 2 years old with a 2 year old. Knows how to type, spell, and read, WOW! Ha ha

But anyways. I wear 2 pieces. But since you're a mom, it depends on how you would like to dress. Some mom's I know that are still young, still do wear two pieces, but if you don't feel comfortable in a two piece, then absolutely a one piece.
