Indian Ladder Farms hosts Baby Animal Days from May 7-22nd. Each day from 9am-5pm you can pet and learn about baby farm animals! Admission is only $5 per child, last time I went Moms were free.
I highly suggest going during the week if you can, it much less crowded and your kids really get some one on one time with the animals. The staff is wonderful and loves kids and it shows.
Chicks, pigs, rabbits, calves, lambs, and more. They also have a really cool playground and picnic tables.
