Just been checking out their website and are made with PUL not PVC... Maybe the older ones were PVC? :dunno:
NONE of my LOs are night trained yet! Even ds1 and he's nearly 5 1/2, in fact I still put them all in nappy/pulls for day naps coz they often have accidents then too :( there's a family history of bwing though so I'm not surprised just waiting it out. Wish it didn't have to be so expensive in the interim though *sigh* ds1 does ask to were jocks to bed but I'm not brave enough to try without him being dry for a week prior which hasn't happened yet. Soon hopefully.
