Log in to share your thoughts Re: Will I 'pop' sooner because I'm having twins? With twice the baby and twice all the accompanying fluids and placenta growth, there’s simply more there to carry.

Ultrasounds for twins? Can twins kick each other? Excerpted from The Baby Bump, Twins and Triplets Edition I’m Pregnant With Twins. When Will I Show?
