Four Months Old

My little man is four months old today. These past four months have gone by so fast. I'm a little sad that he's not the newborn that just loves to sleep and snuggle but I'm also loving all the smiles and giggles. He is rolling over from his stomach to his back all the time and is almost rolling the other way too. I just moved him out of our room into his crib and so far it hasn't been the easiest transition. I'm hoping that this doesn't last too long as I already forget what it was like to live without sleep...
