6-12 Months

The widest part of the JOWI catalogue. At 6-12 months every garment type is available: pajama sets, sleepsuits, zip rompers, bodysuits, rompers, dress sets, lounge sets and two-piece sets.

It is also the size where United States sleepwear rules start to matter. Above 9 months, children's sleepwear has to be either flame resistant or snug-fitting, which is why sleepwear in this size is cut closer to the body than daywear and should not be bought loose. Our guide to United States children's sleepwear rules explains the rule and where it comes from.
