Question: when do you start showing with your first child?
Answer: If it's your first pregnancy you'll probably start to show between 12 to 16 weeks. But this initial bump is not from the baby. In fact, at 15 weeks, the average fetus is 4 inches long, or about as large as an orange. So that "baby bump" isn't from the baby's size, but rather the expansion of your uterus.
