In the interests of research (no not for me) has anyone used itti bitti snap ins on a newborn? How did they fair? Also im using mine with the tri fold pad and booster thingy on top - anyone used un boosted on a little one or even a big one?..... Anyone used them overnight (i have not dared) - my ds was in his from 9 till 2 today and they were not competely saturated so i am tempted.
