What Our Clients Say

“Jeannie went above and beyond to make our girl’s first birthday so much fun with the Berry-themed soft play setup that all the kids enjoyed – so much so that my niece cried when it was time to go. I was so impressed by the berry touches because there was no berry-themed package to choose from, but Jeannie listened to the color scheme I was looking for and purchased the most adorable strawberry plush toys to go along with the theme. Cannot recommend Party Baby enough. Very happy with how the party went. Thank you, Jeannie!”
