i've recently got a baba and boo and a nappy from iwilltosellmore,
they are as far as I can see, exactly the same nappy. No noticable difference in size or materials. The baba and boo one came with two inserts though. They are an excellent fit but they are noticably bigger than my other one size pockets so i'm not sure how great they'd be on a newborn (my boy is 5 months 18lbs). The major difference was the price, baba and boo £9.25 (this was through their website, i'm not sure if they sell cheaper or same on ebay), the Chinese company £3.98, delivered to Ireland. The Chinese one took about a week longer to arrive.
