I'm sorry but I have to ask.....I have a whole houseful of children and have been through some pretty ugli stuff with each of them, but for the life of me, I have never heard of children being de-wormed!!

It has to have another name for a common ailment, I'm sure. Please, please clear that up for me!!
I have had quite a few babies get constipated, and lots of fiber in their diet will help for sure. Plums, watermelons, and blueberries are wonderful and most kids like them. I've had to use stool softeners as well. I've even made up a warm bath with a baking soda solution. The measurements are on the box for soaking. The warm water will help loosen the muscles around the bladder.
If your little one is on dairy, there might be a sensitivity to it. My little girl who is now 4, went from nursing to formula, then we wanted her to go to cow's milk at 1 yr old. She would get so constipated by the end of the day, she was screaming in pain. We had to continue with formula, even as she was approaching 2 yrs. of age because her system couldn't handle processing it. We tried again much later, and watered down her cup of milk and she never knew, and it began to get easier for her to get use to it.
Good luck,
