Uy, I haven't tried Korean diapers myself, but a few of my mum friends swear by brands like Merries and Huggies Little Snuggler (Korean-made), they say ang leak protection talaga napakaganda and hindi masyadong mahal compared sa imported brands, plus mas malambot sa skin ng babies. One of them switched kasi ang anak niya was getting rashes with local brands, but I think it really depends din sa skin ng baba, some kids are sensitive, some aren't, kaya trial and error talaga! Have you tried any yet or looking for recommendations?
