a month ago sis stopped sleeping through the night. she was climbing out of bed at least three times to join us in ours. after three weeks of this we were at a loss of what to do. i attempted to bribe her with special prizes, but she wasn't having it.  the other night i put a night light by her bed and told her it has special sleeping powers. she hasn't woken up since. silly girl. so glad to have her sleeping again.
