I did something similar last year, and Balloon Bar handled it very smoothly. They specialize in personalized balloons with confetti, pastel cascades, and quick delivery. Their catalog on
https://balloonbarae.com/ includes newborn and gender reveal themes, as well as custom text balloons. They delivered to us in the morning, so everything was ready by the afternoon. Helium latex balloons stayed perfect until late at night, and the big reveal balloon was sturdy but popped easily when we needed. Just give them the confetti color and exact wording for the text, and they’ll prepare it all.
