I tried teh water trick with Natalie but she just pees more. It goes straight through her. We had to do the cotton swab trick today. I called my peds office and spoke with the nurse. She said coated a cotton swab with a lil vaseline or KY jelly and insert it into the rectum just less than an inch. You can either swirl it in a circular motion or use the in/out method. She said sometimes it works, sometimes it doesn't. She said if it didn't to try pear, white grape, or prune juice (no more than 6 oz. for the day). That should do the trick. If not to bring LO in to check out any underlying problems. The swab trick worked fine for Natalie, and man was she holding a lot in, poor dear. She felt MUCH better afterwards, it was easy to tell.
