This West Valley farm has something for the whole family: large & mini corn maze, petting zoo, play areas, jumping pillow, bounce house (weekends only), train rides ($2/ride) and tomato cannon, in addition to multiple food vendors. Free for kids 2 and under. $12 per person otherwise (on their website they have a 2$ off coupon).
Come meet, mingle, eat and if needed have an afternoon cocktail while kids can run around in the splash pad close by. Luci's at the Orchard is a cute restaurant with wide variety of lunch/brunch foods, outdoor seating and a splash pad for the kids.
