Butterfly baby sleeping is so cute for your baby shower invitation!!
You may change the wording on the design to say anything you like.
Some examples are:
We're fluttering with excitement and happy to say
a sweet baby girl is on her way!
A baby caterpillar lies in rest
A beautiful buttrfly soon will be our guest.
