Waking up in the middle of the night

Waking up in the middle of the night to Matthew's cries are nothing new. Usually he just needs his Nuk replaced or a little comfort. Last night he woke me around 3:00 AM and I went in to check on him. He was Nuk-less again so I searched around on the floor and found on for him. I noticed he was still wrapped up in his blanket, which was unusual. He usually would be standing and point to where his Nuk was, so I thought he might be cold. After all, it was cold out last night, for San Diego that is. He sleeves on his pajamas were pushed up so I pulled them down to his wrists again and he responded with "tickle, tickle, tickle". It made waking up in the middle of night worth it.
