Gender Reveal TWIST

So we had a gender scan at 18 weeks & found out that our sweet baby was a boy!

At 19 weeks, we had our gender reveal party.

I am 22 weeks now & we had our anatomy scan today. Our sweet baby is healthy and growing right on track at 1 pound 2 ounces.

However.....

Needless to say, we are SHOCKED! But, thrilled nonetheless.

Now I need some clever ideas to announce to the world that our original scan wasn't right & we are having a sweet baby GIRL!

Help me out ladies!!
