It depends on when you want to take the pictures. If you wait a little bit many of the bulbs will be out and blooming. Bay Area Park has a little Japanese garden. In a month or so, it will be in full bloom, and it's just stunning. There are patches throughout the area that a baby could crawl around in.
I KNOW there are more locations, but I can't think of any right now! Lol! I hope some other moms will chime in for you! :)
HTH,
