Very good question. This seems to be a common issue among toddlers due to their picky diet. My main concern is that it was been 2 weeks since a bowel movement. At this point, you ruled out her diet. The next step is to try a laxative such as OTC Miralax. You can start by giving 1 tablespoon twice daily. It will take about 12 hours to see any results. If hat doesn t work, I would try a glycerin suppository. For kids, they come as liquid glycerin that you insert rectally. if it doesn t produce a stool within an hour, I would have her evaluated in the ER for a possible blockage. There they will have to possibly do a fleet enema or give some very strong medication to break it. Let s cross our fingers and hope that the Miralax will work! Good luck!
