M is almost 18 months and has struggled with constipation for a long time now, especially after switching to WCM. Dietary changes (I've tried them all!) have not really helped. The only way that we are controlling things now is by giving her a daily bottle of prune juice and water. She takes her milk and water from straw cups but she will only drink the juice from a bottle. I would love to ditch the bottles entirely, but I need another way to keep her regular.

Do you give your toddler probiotics? Do you think they help with constipation? What kind do you buy?
