My son is approx 13kgs and the green kids do fit they are just pretty tight and im thinking he's going to be in them for another 12 months probably and i really dont think they will fit him for that long. I have heard a mixture of good and bad about pea pods, i just dont want to be the unlucky one who gets them and wastes my money because they dont work. The reason im looking at these brands in particular is because i work in a natural and organic baby store and these are the brands we stock and i would like to buy from my work preferrably. We also stock bum g but they come with a microfibre booster and i dont want to use microfibre, i would like a bamboo or organic cotton booster. ill look into the other brands you have both mentioned because as much as i would love to get them from work and support the business getting the right nappy is a bit more important! Thanks for your help!
