Bless my dd, she's nearly 6 months and 17 lbs and has a gorgeous chubby bottom and thighs. We have just gone over to reusables at last and I'm struggling with trousers and dungarees (can't be faffed with dresses and tights although may have to if no-one can help) that fit. I have just bought some in the next size up (6-9 months) but they just seem to be longer rather than bigger round the bum. I would also be interested if anyone knows of any fairtrade stuff that isn't prohibitively expensive or shops that aren't too bad in terms of overseas labour (given the recent press on asda, primark etc)
