Using this Playgo Shape & Stack Bundle is super easy. Just let your child pick up the pieces and start stacking them in any way they like. They can also sort the pieces by shape or color. It's a great way to keep them entertained and develop their creativity. When it comes to safety, always make sure your child is supervised while playing, especially as they're under 3 years old. For maintenance, you can simply wipe the pieces with a damp cloth. This will keep the toy clean and ready for the next play session.
