I bought these, advertised as mittens for "baby boys", but they're way too big for my 4- month-old, and he won't grow into them in time for winter to be over. In retrospect, realizing that baby/infant hands don't grow like chubby baby bodies, so think twice on whether these would fit your baby. Would be wiser to get a coat or warm quilted infant inserts with covered hands, as babies' slow-growing hands are hard to mitten.
