We used the Bobby Lounger a ton when Archer was a newborn. It was where he napped if he wasn’t sleeping on us. Of course, we never left him unattended in it, but we found that he liked the snugness of the pillow and didn’t have to be swaddled in order to fall asleep. This was only used during the day, at night he slept in his bassinet.
Archer never developed the flat head syndrome which I heard some Moms say their kids had as newborns when they slept in the bassinet that comes with pack n’ play. I don’t know if this is the case since we don’t have a pack n’ play, but we never had that issue and found this to be very useful during the first few months.
Again we only used it for him to nap in during the day or to sit in while we ate dinner and needed both hands. It is important to have them lay on the floor so they can kick and squirm freely. I think the tag on this product says don’t use for sleeping so know that we may be breaking the rules on this one so use at your own risk, but again, we only used during the day and never left him unattended while napping on it.
