A Baby in a Tub??

Mrs. Deanne was telling Michael about the baby in her tummy, and she told Michael that she was going to have the baby in a tub, so he of course was curious and Mrs. Deanne showed him a picture of the tub. Then they counted the number of months until the baby was going to come out of her tummy, and coincidentally it is the same number as Michael's age. So we were trying to explain the difference between months and years.
