these sleep sack be so cozy for the little one . it give I a great feeling of comfort know that my guy would not end up tangled in he blanket at night . we keep we house cool during the winter time so we could dress he in normal pajamas and still use this sack . in the summer time we would put a short sleeve and shorts pajama set on he and use this sack . he never wake up too hot or too cold so I think they work great . cream color be nice and neutral for either gender .
