To use this Barbie playset, first, take out Barbie and her baby doll patient. Dress Barbie in her pink heart - print scrub set. Place the baby on the examination table with stars overhead. You can use the accessories like the baby bottle and stethoscope to play out different baby - doctor scenarios. Remember, the doll can't stand on its own, so you might need to support it. As for maintenance, keep the set away from rough play that could damage the accessories. If it gets dirty, you can gently wipe it with a soft, damp cloth. Also, since the colors and decorations may vary, don't be worried if your set looks a bit different from others. This set is designed for kids aged 3 and up, so make sure younger ones are supervised during play.
