This is a set of six newborn baby clothes: five short undergarments and one romper undergarment. The size is 50 cm. These are used items that my child has worn, so there is some wear and tear. I think you'll need a lot of changes of clothes, so how about these as spares? I wash my children's clothes separately, and I don't use a dryer! I generally plan to ship within the next day or two, but please understand that there is a possibility of delays due to unforeseen circumstances such as a sudden fever in my young child!
