Chelsea is exactly the same Larissa.
She can go 2-3 hours without weeing & then once she wees the nappy is soaking & her pants get all wet

Unfortunately, trim nappies & heavy wetters just don't go - well at least that has been my experience.
If I Chelsea's not wearing longies, I have to change her pants at least once a day atm. It's driving me crazy!!! The sooner she TTs the better I say
