My daughter suffers with constipation, and sometimes needs a little bit of security! So I use Dry Like Me Training Pads, they are also great for potty training. They are normally £3.49 a box but Sainburys have them at £2.32 at the minute for a box of 18. I know this won't be of use to most, but its saved me a bit as I have stocked up! They had them in the Leicester Fosse Park store.
