Hi K.,
This may sound a little crazy, but when my son was a toddler it was recommended to me, by whom I cannot remember, to give him liquid jello. I would simply make it and while it was warm allow him to drink it. It was to help bind him up. Honestly, I can't remember if it worked or not but maybe someone else with a toddler may have heard of this more recent than 10 years ago when I tried it. Good Luck!
