Leo's Big Boy Bed: Take 1

Since we would be traveling a lot this summer, we decided to put Leo into his toddler bed.  It lasted less than 2 weeks.  At first he would sleep and only get up occasionally.  It was great.  Then the nightmare began.  He would get up around 2:00 am and barely sleep again unless he was with us.  When he "slept" with us he would be sideways, kicking, crying....etc.  The lack of sleep caused me to be extremely grumpy and it was tough to function.  I was like the walking dead most days.  So back up the crib went.  He seems happy.  He is sleeping through the night, but back to getting up around 5:15 am EVERYDAY.   Even though he gets up early, I am guessing he will be in his crib until he goes to Kindergarten.  Getting up early is better than not sleeping at all right??
