Little explorer

Owen has started taking his curiosity all of the house. I think he has opened every door and looked in every corner he can get to. He also learned how to climb the steps recently. One day I looked away for a minute and when I looked up again I just saw 1 little foot peaking out from the bottom of the stairs. He slipped on the third step and bumped his face a little bit which stalled him for a few days but he tried again and made it all the way up!
He's been nursing more often and eating less table food and I'm not sure if one is causing the other. I have no intention of weaning him any time soon since that is not a battle I want to deal with. He's nursing usually 4 times a day but usually asks more often than that.
He's been signing a lot lately which is fun but he has about 3 signs that mean 6-7 things.
I counted the other day that he knows about 10 signs but doesn't always use them. He'll properly sign milk, eat, all done, fan and used to say more correctly but now more, please and eat are the same. He'll occasionally sign bird, dog and water. Owen also learned to pray before his meals which we love. We'll put him into his highchair then say "let's pray!" And he'll put his hands together while we pray. We borrowed some Signing Time DVDs from the library several weeks ago and he seems to enjoy them and I think they've helped him learn.
Owen hasn't been feeling well all day. He's been running a fever of around 101-102 which is sad to see but I'm loving the cuddles I'm getting. I think he may be getting molars in because he's been trying to chew on stuff in the back of his mouth. He ran a fever when his top teeth came in too so maybe that's all it is. He slept about 4.5 hours today so I'm hoping he still sleeps tonight and feels better tomorrow. Since we were traveling 2 days in a row he didn't get a real nap in either of those days which probably wore him out as well.
