I had a baby shower for my second... In my defence, it was my friend's idea, she said just because it's my second doesn't mean it's any less important. We basically sat around chatting and had some afternoon tea and I got some little gifts.

I think Lime is right and sending another message might be a good idea. She might have thought "I know she doesn't normally do showers but she might make an exception for me" or something! Just let her know what's going on.
