These work great! My son has sensory issues and would hold his poop for DAYS. I was desperate for help, and these were the answer. Of course, he did not like getting one, but the applicator was very small which made me feel more comfortable that I would not hurt him. Also, it is a tiny bulb that they receive so it is over very quickly. Sometimes he didn't even know it was coming until it was over. The added bonus to this ordeal is that I believe these were the key to helping him understand his bowel urges better. He soon started going on his own, and we have not used one for several months. Very grateful for this product!
