DS2 (21 months) is becoming really, really wriggly on the changing mat - no amount of nursery rhymes can stop the fighting. I'm thinking of ditching the mat and changing him standing up (he's perfectly happy putting on pull up nappies for swimming). If I do, do I need to invest in stupidly expensive Pull-ups or Little Walkers? Or can I do a normal nappy standing up? And can you successfully change a poo-ey nappy standing up? (These may sound like rather dim questions for a second-timer, but my first son would happily laze on the changing mat for hours - even fell asleep on it once 
.)
