I'm using cotton terries and a few shaped cottons (easy peasy) with mothereasy and bambinex wraps. 4 weeks old baby, poo always touches edges of wraps and sometimes just explodes onto clothes, wee also leaks in leg area/side top. He is 11lbs but the terries are just hughmongously bulky, muslins are not enough and the shaped ones don't contain explosions. What am I doing wrong????
