Informative fetal size guide

A fun way to visualize your growing baby: real-life size references (fruit and everyday objects), trimester by trimester.

Growth summary by trimester

• 1st trimester (Weeks 1–12): From a poppy seed to a lime
• 2nd trimester (Weeks 13–27): From a pea pod to a corn cob
• 3rd trimester (Weeks 28–40): From an eggplant to a watermelon

Want the week-by-week version? Open the Development section on your Pregnancy tracker — it shows the size comparison for whichever week you pick, not just the trimester it falls in, and updates automatically as your pregnancy progresses.
