Long process to the big boy bed

Over the past few days, we took Dylan's crib out of the attic and set it up into a full size bed and got a box spring and mattress for it.  With a new baby coming in August, it is time to start getting him into his own bed.  Tonight, Daddy read him some books, put on his fish night light and shut the lamp off.  Immediately, Dylan sat up and said he wanted his Mommy and didn't want to do this tonight.  We did give in right away because it was 8:30pm and past his bedtime.  I told him tomorrow night, I'll give him daddy's pillow and my book light and we'll try it again. After co-sleeping for 4 years, we all know it is going to be a long process but we have to start somewhere.
