I just got back from visiting a friend and her 3 week old ds. He has reflux so of course prefers to be upright. He likes to sleep on her chest but gets very upset if he's held tightly against her (in her Bjorn, my babyhawk, or just in arms). We think its because the pressure bothers his stomach. Is there a carrier that will hold a newborn upright without squishing his tummy? She is very new to babywearing so I'm trying to keep it simple for her.
