My just potty trained daughter still has accidents. If it's just a LITTLE accident the plastic lining in these underwear save the pants. They are still absorbent and comfortable for her. I plan to get more, I wish I hadn't bought so many pairs of regular underwear. The higher cost of these undies are worth it when you consider the time I spend over time rinsing pee pee pants before I throw them in the regular laundry.
