Marcos just turned 6 months 2 days ago. About 3 weeks ago he got up on all fours. He'd try to move both hands at the same time and fall flat on his stomach and face. Since then he's been trying to crawl, and he's finally perfected it! A few days before he turned 6 months, he got his hands and knees working in the right order, and he's been motoring around ever since. An honest to Pete crawl!! And every day, he is doing something else. He can now also stop and get his butt under him to sit up; climb up the one step of our sunken living room
; and pull up to a standing position on any furniture with a hand hold. He is thisclose to cruising! Man, I thought I had months before I had to think about this stuff. Lula didn't cruise on furniture until she was 9 or 10 months, I think.
And he's tiny! I'm not sure he's 15 pounds yet. :LOL
There's such a wide range of "normal", but I do think this is on the early side. It's kind of exciting, though, isn't it?
