Why do they grow up so fast...

My 6th month old little boy slept in his bed last night. Not through the night but he didn't fight it we had been co sleeping. He has two teeth about to come out. He will like a vampire for a little bit. It's the ones next to his two front teeth either side that will be out any day now. I'm at work today my DH calls me saying he got video of him trying to grab his feet my pulling on his pants. And then I get another call from DH saying that he said his first word... Mama... it's going by to quick. I'm just trying to soak up every moment!
