For those of you that chose to use a pack n play instead of a crib, how long did you keep your baby in the "bassinet" area? I know most say that there's a 15lbs weight limit. Did you take out the bassinet part before, at, or after 15lbs? If you waited until after, at what point did you switch and did you have any safety concerns? I tried switching at 13lbs (4months) but she hated being all the way down there so i put her back up, she is 5 months now and im assuming she is around 15lbs or a little under but I'm debating buying a crib and moving her out of our room or giving the lower part of the pack n play another try and keeping her with us for a few more months.
