Logan's blanket

This kid loves his blanket! He takes this thing everywhere with him. I thought it was so cute how he was dragging it between his legs so I took a picture. But he really does love this little blue blanket and it's kind of become a recent thing. I guess he started to get attached to it about three or so months ago. When he starts to get tired or he's crying about something he has to have his blanket and when he finds it he just pops his thumb into his mouth and he's a happy camper. He's also become quite the climber. Afton and Dax never did the whole climbing thing and getting on the counters, but Logan is the opposite. He's figured out how to push chairs over to the counter so he climbs onto the chair and then up onto the counter. He also likes to climb onto our table and walk around on it. It's great! No, not really. I can't leave him alone for a second because I'm afraid he'll climb up onto the counter and fall off. I don't have any pictures of him climbing on things, but when I get one I'll put it on here. He also loves to throw things and his favorite thing to throw right now is his food. Every time he's in that high chair he throws his food and he laughs when he does it. The little stinker! It drives me nuts! I'll tell him "No!" and bend down to pick up the food and then he'll throw another piece of food. Oh and he also loves to throw stuff at our television. And he has quite the arm so he actually has pretty good aim. Hopefully he goes through this phase very quickly. Any tips on discipline for a 19-month old?
