Yep, same here too. I just brough DS and DD new shoes and DS's shoes were a bigger size than DD's!! He's 16mths younger than her. In his wardrobe we have size 0-2, in DD's wardrobe from sizings 1-4. It all depends on the brand of clothes and what it is (eg, pants/tops/jumpers...). A real pita when someone asks 'What size is she/he?' It sounds kinda funny saying 'Ummm, I'm not sure?' I'm their MOTHER I should know!! LOL
