The bump - measurements between 20 and 21 weeks!!

I've just been having a sneak preview on the Bump website of baby's size etc for week 21 of pregnancy.

Up until now - baby has been growing .25 or sometimes .5 of an inch in a week.

This week apparently she's going from 6.5 inches (cantaloupe) to 10.5 inches (banana)

That's some growth spurt!! Or are the bump now measuring head to toe rather than head to rump??? 4 inches in one week is a huge gain in size!
