Woe is me!

I'm such an idiot! My nephew and his wife are expecting their first baby in a couple of months. Naturally I thought I'd make them a quilt. In fact, I thought I'd make two as they don't want to know the baby's sex in advance. I took a lot of trouble putting extra wadding under the motifs and quilting round them to make the whole thing nice and puffy. Not to mention stitching in the ditch round each block. I checked it numerous times during the process but it was only after I finished that I spotted the (most definitely not) deliberate mistake:

Now what do I do? Cross my fingers and hope it's a girl?  I think I'll probably just make another and hide this one at the bottom of the pile.
