Nostalgia at Naptime

I'm feeling a little sad/nostalgic. My baby is closing in on 3 weeks old already. Time seems to be moving at lightning speed. I'm really trying to focus and enjoy each day AND each night time feeding.

And my 3 year old? No longer wants my help to get to bed for his nap. He likes to close his door and crawl up on his bed without me. When did he get so big?
