New Year's Resolution. . .to sleep!

So Cooper is finally feeling better and now we have a new problem--to break all the bad sleep habits we developed in the month of December, including. . .sleeping in Mom & Dad's bed.  Those who know me are shocked that I allow this.  Cooper is our second child and only he has spent time in our bed.  With Paige I had the fear that she would never get out if we let her in, so the poor kid knows its okay to climb in during the morning hours and cuddle and watch cartoons, and that's it.  I gave in about week 2 or 3 with Cooper in December and realized I could not sleep in the rocker in his room anymore and brought him in.  We have a king size bed, should be room for one small boy.  WRONG!  It worked well for a day or two and then he started moving and rolling sideways, etc.  I realized we created a monster.  Friday night I decided he could tough it out in his crib as he was feeling better and infection was gone.  He screamed and broke the crib latch on the side that drops down so it won't stay up; and he was going to bail over.  Sigh.  Next day the toddle race car bed came out.  Moderate success with sleeping until 4am, and then a mom cuddle.   A few days later and Ryan or I are sleeping on the floor beside the toddler bed.  Not a solution.  So I had a momentary temper tantrum last night and put his crib mattress back in his crib, tied up the side railing with a dishtowel (it was 3am) and let him cry for 20 minutes and then enjoyed 3.5 hours of sleep.  I just hope it only takes a few days of him screaming to realize this used to be the normal routine and he likes his bed :)
