sleep

I have been having trouble sleeping for the past few months now. My shoulders hurt. They've been hurting for a few months now , but only at night. IN the day time the are sore but the pain is a lot less. The pain makes it hard to retuen to sleep when I wake up. Also my youngest son (almost 2 now) has been waking up at 4-5 am. Normally he wakes up at 8 am bu tthis whole 4/5am thing is driving me batty. He is a climber. He can now climb out of his crib , on the counters , can push his chair to open the kitchen drawers to grab knives, can climb the tree house out back. ........ Sorry if this is just a rambling note. Im tired and cant quite go to sleep. My job depends on me being pleasent to folks who come in to buy a car. Normally I am quite nice , but the past few days its been a mask I put on when I get to work.
