Having two kids close in age has it's trial and tribulations.  It was to great relief and comfort that the Graco Papasan Swing and Bouncer came into my life.  My youngest child was not the best sleeper at all and had her days and nights mixed up for awhile.  I found that she slept so much better once we started putting her in the swing.  It would keep her comfortable until she fell asleep, often giving me an extra half an hour to an hour of sleep for myself.
