Super Close to Needing to Fully Babyproof

On Saturday my Dad came over to make breakfast for us and hang out for the day.  In the afternoon I put Aaden down in his crib for a nap.  Well, my Dad went to check on him and he was in his crib with his arms stretched fully out through the slats, playing and sucking on a plastic bag!  Holy sh!t!  I'm glad my Dad went and checked on the little monkey.  The plastic bag was sitting on top of a bin that I have next to his crib, I didn't even realize that he could reach it.  It honestly didn't even cross my mind.  I know everyday I'll find more and more things that have to be baby proofed - or Aaden proofed, I have a feeling he'll be into everything.
Aaden has mastered getting to sitting from laying down just over the weekend.  It's a pretty nice milestone because now I don't have to go pick him up when he ends up on his tummy and starts fussing because he's stuck.  I'm thinking he's only a few days from crawling.  He has all the movements down he just hasn't put them all together yet.  He gets up on all fours and rocks.  Or he'll bury his head and get his butt in the air and start moving his legs in the crawling motion but doesn't go anywhere.  He gets on his belly and stretches as far as he can to try to reach something.  He is literally so close.  I think once he wants something bad enough it will entice him to move.  He has been a bit fussy lately, I think it's because he is so ready to finally start crawling that he gets frustrated that he can't.  This boy wants to move!
He did not sleep well last night - and now with the sitting thing, I walk into his room and I find him sitting up in his crib crying.  I admit it kind of freaked me out at first just because I wasn't expecting it.  He's also started being able to pull himself up in his crib better so I'm sure it won't be long til I find him standing in his crib crying for us.  I fear the days of being able to pop his pacifier back in, giving him his blankie and him falling right back to sleep are going to be long gone.
Also - he is starting to dance to music - it's way cute!  Every time some music plays from one of his toys, his starts shaking his little body :) (hopefully he'll have more rhythm than me!)  And he's also trying to learn to clap.  My mom plays patty cake with him all the time and he loves it.  As soon as you start singing it and clapping, he turns towards you with a big cheeser.  I've noticed him trying to clap on his own too but damn those hands are just so hard to get together!  (Usually his arms are just flailing around in front of him but he's trying :) )
