I just stocked up and bought DS several pairs of PJs - the Dr Seuss and Gruffalo ones are too cute! - and underwear and nightgowns for myself. Their 'undies', as we call them in Britain, are the BEST - way better than anything I've found over here, and very reasonably priced. The exchange rate is great at the moment, too - £1 is around $1.50, so you get a lot for your money.
Check it out!!
