Onesie Assembly Line Race

Set up a station with plain onesies, fabric paint, markers, and simple stencils.

Divide guests into small teams, each assigned one step such as stenciling, coloring, or adding a message.

Pass onesies down the line assembly-style, with each team completing their step before passing it on.

Set a time limit for how many onesies the group can complete together.

Lay out the finished onesies for the parents-to-be to keep as a full set.
