Prone to spitting up, vomiting and general fussiness, our pediatrician suggested she might have acid reflux and to keep her upright at all times. During the night, and after feeds, I would hold her for hours and hours, my arms and back aching, my mind and body exhausted from lack of sleep and sitting still for so many hours.
We set out on an expedition to Babies R Us to find a bed that would do the job of my aching arms. We settled on this chair that was angled specifically for babies that have reflux issues. It worked well for a month, but she thrashed her little arms and legs back and forth kicking off her blankets and snorted like a little truffle pig at night in this position. It was also a pain in the rump to lull her to sleep only to then manipulate her into a (particularly loud) velcro harness. After a month, we went back to swaddling.
