Common Questions
How big is my baby right now?
Use the calculator above: enter how many weeks pregnant you are (or your due date) and you will see the fruit or veggie comparison, approximate length, and approximate weight for your exact week of pregnancy.
Why is baby size compared to fruit and veggies?
Fruit and vegetable comparisons make it easy to picture how much your baby has grown each week, from a poppy seed at week 4 to a small pumpkin at week 40. They are friendly estimates, not exact medical measurements.
Are these baby sizes accurate?
They are widely-cited averages. Every baby grows at their own pace, so your baby may measure a little larger or smaller. Your Garden OB/GYN provider tracks your baby’s growth with ultrasound and fundal-height measurements at your prenatal visits.
When should I start prenatal care?
As soon as you know you are pregnant, ideally in the first 8 weeks. Early prenatal care helps keep you and your baby healthy. You can book a visit with Garden OB/GYN at our Brooklyn, NYC, and Long Island locations.
