Lots of lovely new/ growing bumps!
Ramona - yours is very high, neat and round
teachmath - your bump is gorgeous too, you are still so slim elsewhere
kaleighdaisy - looking fab in maternity gear 
tashiebaby - definite bumpage there!

and 20 weeks where I have just moved into mat gear and looking markedly pregnant!
