3 DAYS.... 3 DAYS in a row DS is waking up at night for 2+ hours and laughs and giggles.

Friday night: I was suddently awaken at 4:43am (to be exact!!) from a belly laughing boy. I thought he was dreaming. But no, he was babbling, etc... for 2 HOURS!!!! At 6:30am I came finally in his room and gave him a pacifier and he went back to sleep for 30 minutes.

Saturday night: 4am... again laughing, walking in his crib. Eventually 2 hours later, back to sleep.

Last night: 2am. Same deal until 4:30am.

I can't take it. I am overly exhausted. I had to work this weekend and I could barely survive since my job is rather physical. I have been getting a max of 5-6 hour of sleep per night for the past 3 days.

What is going on?

I cannot even imagine tonight.

Anyone else has a toddler that JUST wake up in the middle of the night and cracks himself up at 2am?
