Grace wore an XL Fuzzi at night once she had TT in the day, but it was always sopping in the morning. At 3.5yrs we decided to go cold turkey after reading some info that said that for heavy-sleepers it's best to put them to bed with a completely bare bottom as any kind of pants or trousers will have them believe that they're wearing a nappy and in a sleepy state they'll just wet. We decided to give it a go so we bought a mattress protector, put her to bed with a bare bottom, lifted her at 9pm (she'd been asleep since 7pm) and put her on a potty next to her bed, and in the morning she was dry!! We couldn't believe it! The same method has been working ever since, although now that she's 4.5yrs she can wear pj pants to bed without wetting, although she prefers the bare bottom!!
