What Are The Ideal Weights For My Twin Babies (during the pregnancy)?
What are the Ideal Weights for my Twins?
As you progress through your twin pregnancy, you're likely going to be receiving many updates from your doctor through ultrasounds and other methods on the weights of 'Baby A' and 'Baby B'. While the chart below indicates average gestational weights for a singleton pregnancy, your twins are likely to be close in weight to the chart below if they are measuring at the average levels - our unofficial surveys of twinstuff.com board visitors who delivered births in 2002 and 2003 have paralleled the weights of the singletons' figures shown below.
The below table was taken from 'Ultrasound in Pregnancy: A Book for Parents and Parents-To-Be' by Dr. Applebaum. The table is just meant to be an average weight and should not be construed as medical advice of any type. The final authority on the proper weights of your babies should always be your OB-GYN doctor.
