My son had the same problem. For about the first 6 months of his life we always had the Pedia-Lax Liquid Glycerin Suppositories. They work faster (like almost instantly) than a regular suppository because they don't have to dissolve. They come in a bulb like syringe they are a ton easier then tiring to use a suppository. I never gave him the entire syringe full but a little went a long way. It worked in minutes and he was a much happier baby because of them. I would recommend them over hard suppositories. Plus my son seemed to not be in as much discomfort with the liquid ones. Hope this helps.
