All items are H&M newborn size underwear and rompers. ◎ Undershirts: short sleeve, 4 pieces (50cm) ◎ Underwear set: long sleeve, long pants, 2 sets (55cm) ◎ Romper: 1 piece (50cm) I used these from birth to around 2 months old. My child could wear them up to 3-5kg. I wore each item about once or twice a week until around 2 months old. I washed them separately, using only Arau detergent. I wore the 55cm sets or rompers over the 50cm undershirts. They are simple, and above all, the pants have a proper length, which is rare for newborn clothes, so they were very good.
