The Children's Museum in downtown Phoenix is celebrating National Grandparents Day on Sunday with two free events.
From 9 a.m. to 4 p.m. on Sunday, grandparents and their grandchildren will get free admission to the museum.
Grandparents get free admission when they bring their grandchild and vice versa.
"I think everybody recognizes the very, very important role that grandparents play in children's lives," said Marion Wiener, a 'playologist' at Children's Museum. "There's a very special connection between grandparents and grandchildren so we like to celebrate them."
On Friday, Sept. 12, from 5 p.m. to 7:30 p.m., the Children's Museum will be open after hours for a Grandparents Dance. Grandparents will once again have free admission when they bring their grandchildren.
Regular admission is $11 and children under the age of 1 are free.
