off schedule

i've probably mentioned this before, but i keep my kids on a regular schedule. it is a lifesaver for a working mom. something has been off with gillian this week. on tuesday night she had a hard time falling asleep and then the fire station behind our house turned on the fire whistle. she (of course) woke up. not john - he is like his mommy. he will sleep thru anything. last night, gillian had another rough night. i put her down, while she was awake. she entertained herself for awhile. and then she started screaming. we went running to her and discovered a huge knot on her head. she must have hit her head on the crib and bruised immediately. the worst part was trying to put ice on the bump. she hated it and cried. tonight, she didn't want to go to sleep again. i had to rock her to sleep. something is different this week. the only thing i can think to explain it, is her teacher has been out sick this week. it's funny how one little thing can mess with the schedule or routine.
