I wanted to have it increase their fun but could only get that to work for toddlers and sims would no longer place infants in the swing with it coded to increase fun. It doesn't actually swing.I'm so happy to get it to actually work for infants that I decided to share it now. This swing was requested by CarolynBetty and I though it was a wonderful idea. Are you tired of your sims leaving the babies on the floor all the time? Then this swing is the ticket for you.
