What Our Customers Are Saying
As a social event planner, I worked with Party Baby this past week for a client’s son’s birthday party. Jeannie was so easy to work with, adhered to our color palette requests, and set-up according to our timeline. The play-set was a huge hit with the kids and fit perfectly with our spring chicken theme. I highly recommend Party Baby and would use their service again in the future.
Fantastic experience and it was the highlight of the party!! The team was responsive and helpful. They showed up right on time and got everything set up. Everything they provided was perfect and I will absolutely be using them for parties in the future!
We chose the cotton candy package from Party baby Seattle . It perfectly matched our pastel color scheme, I appreciated the options to customize the colors , set up and take down was taken care off well and most importantly, the kids loved it !
