Proper size when buying baby bodysuits and overalls
Before purchasing baby bodysuits and coveralls from the parent, ask about the baby's body length.
Baby clothes are often not only labeled with the sizes, but often also specifying the size, for how many months the part is suitable.
As I have stated, you can not rely on it at all. From manufacturer to manufacturer, the size is different. A size 68 corresponds to the size of the next manufacturer 74th
Now grandparents, uncles and aunts are delighted with the cute baby things and often eager to buy something for the baby.
I think it best to ask the child's parents for the current body length and go shopping with a tape measure. Especially in suits with integrated feet like a warm overalls you can experience surprises otherwise. And always leave 4 cm of latitude - the little ones seem to grow while looking.
