A phase?

Today I am running on about 2 hours of sleep and I'm exhausted!  Not to mention I worked a 10 hour day yesterday.
 Lately Boston has been REAL clingy.  To the point that he has cried everyday for almost a week when I leave him at daycare. (Arms stretched out, screaming and all!)  It breaks my heart!!!
He has also had trouble sleeping through the night for the past week or so.  He gets up crying around 1:00 and wont stop until I pick him up. I have been putting him in bed with us and he flips and flops for the rest of the night. I try to put him back in his bed and he screams and I can't stand it. I am really hoping this is just a phase or growth spurt of some kind.  I LOVE that he wants me and he has been such a momma's boy lately.  But at the same time we need our sleep. Does anyone have any advice??? I feel like we are back in the newborn phase!
