I would suggest going to Cornbellys at Thanksgiving point. This might be a little scary for the 1 year old. Not sure if they charge for little ones.
I'm not sure the 3yo or the 1yo would like it much. I really prepared my son 5yo before we went. Although they do let the little ones carry a glow stick to ward off monsters, the little ones might not understand. Try a corn maze, I think they would like that much better
Prices for the haunted circus would be $15 per person too. Im not sure if kids under a certain age get a different price though. I'd recommend something at Thanksgiving point instead
Its not a place for kids that young. Its a haunted house meaning you walk through pitch black semi trailers and people scare you.
We have had a lot of little kids walk through and some were more amazed then scared
