It is going too fast

I can't believe how fast Seth is changing now. Every day is so different. He picks up new things constantly. He started to move himself around the room with amazing ease - surely its just too soon! I put him down in one place in the living room, turn around, literally 1 minute later and he is in a completely different place, facing in the opposite direction!! I never thought I would be having to worry about things I had lying around so soon. I was sure I had all the time in the world!
