I've been helping my sister in law with the christening arrangements for her DD next month. She's been looking around for girls pretty frilly baby pants for the occasion, but they need to be waterproof to go over a terry nappy. There don't seem to be any around. There are loads on eBay, but none with a plastic lining, most are a cotton or similar material, ok to go over a disp.nappy. The obvious answer is to use a disp. on the day, but SIL is a reusable nappy fiend! I've suggested putting plain plastic pants over the terry to do the job, and some cotton knickers over the top, but that could be a bit bulky. Any suggestions?
