Dry Like Me and party pack                                                                                  
Dry Like Me are award-winning potty training pads that can reduce accidents. Developed by two mums, they are disposable pads that fit in a child's pants and make it easier for them to wear their own underwear while potty training – which most parents and professionals believe is the best way. Children become aware of when they have had an accident and so start to learn their body's signals that they need to go to the loo. 

While they are learning, Dry like Me capture small accidents and so reduces the mess and stress of accidents. Dry Like Me have proved so successful that they are now sold through supermarkets including ASDA, Sainsbury and Morrisons. They cost around £3.49 for a pack of 18. For more information see www.drylikeme.com.

Now the mums who created Dry Like Me are offering the chance to win a pack that will not only help with potty training, but with your child's next birthday party too.  Three winners will receive a "Birthday Party in a Box" for 16 children, which includes jungle-themed party invitations, party bags, plates, cups, napkins, a table cover and banner, plus three boxes of Dry Like Me – worth £50 in total.
