Hundreds of people will be on hand selling second hand children's clothing, toys and maternity items.
The show is put on by the North Bay group "Just Between Friends". They say shoppers could save big money on some of the items every child needs.
People who want to sell items on consignment have until 12:30 p.m. today to get them in.
The show opens to the public at 9 a.m. on Saturday and Sunday.
