Mr. Leo certainly has been keeping us on our toes. Climbing onto chairs (and preferably the table) is high on his list of hobbies. By the end of the day, our chairs are backwards towards the table, up against the wall, anywhere I can find to keep him safe. This spot by the light switch is a favorite for both Leo and I -- it gives him the power of the ceiling fan without the ability to cause any damage. Perfect.
Leo loves tight corners. He finds a way to squeeze into the tiniest places. 
If there's a garbage can to empty or tupperware to toss once he gets there, all the better.
At his well-baby check in mid-January, he was 31" (97th percentile) and 20 lbs 13 oz (50th percentile). He must have passed the 20 pound mark around nine months (unlike Peter who hit that around 5 months, ugh). He'd just started a nasty two week cold that ended with 3 days of 102+ fever last weekend. Thank goodness we seem to be past that sucker.
He's getting a little gutsier standing. He took one step Christmas Eve and two steps for the first time February 3rd. He seems to stretch farther between cruising objects and will walk across the room loosely holding my finger. At some point he's going to realize that he has the strength and balance to take off walking.
Leo has gotten serious about his food recently. He wants to EAT. A couple weeks ago, I started giving him solids more than once a day--often Cheerios and maybe fruit at breakfast and whatever is soft enough at dinner. If he's not asleep while we eat lunch, I find something for him then, too. He tends to drop about half his morning food on the floor--I swear he's putting it somewhere to eat at his convenience later. His digestive system seems to have caught up with him--he's back to pooping once a day.
We're starting to get decipherable syllables out of him--this weekend my dad got him to say "no no no no" whenever he went somewhere he shouldn't and that has stuck. He says "ma ma ma ma" only when desperate, "da da da da" regularly, "uh oh", "ta" for light/fan, and "na na na" occasionally for nurse or Nana, my mom. He's beginning to try signing -- he signed "more" at dinner tonight, signs "daddy" regularly, I've seen "all done", and waves a lot.
He fights me while pottying him these days but I'm focusing on Peter's pottying these days (one week without diapers--whoo!) so I'm not too hung up on it. I've been letting him go bottomless around the house more--sometimes cleaning pee off the floor seems like less work than wrestling him through a diaper change.
I keep falling asleep with him at bedtime (around 8pm) and usually get up between 11 and 1 for a few hours. It doesn't seem like the healthiest approach, but I get some time to myself that way. So long as we go somewhere in the morning, he's been napping well in the afternoons. He usually takes a 10-20 minute snooze in the car around 10 am, then falls asleep on the way home about 12:30 and sleeps for 2 or 2.5 hours. He's taken a couple 3.5 hour naps recently which feels like an eternity. On Sunday, Dan, Peter, and I were awake without him all afternoon and it was so weird. We did all the Leo-unfriendly activities with time to spare.
Leo's favorite toys are whatever Peter's playing with. He likes playing "catch" if someone rolls him a ball and he'll push it back. He likes putting things in and out of containers. He's trying to stack blocks, but mostly just pushing them over. He vrooms cars along the floor. He lets us read him books, so long as he can turn the pages in random order.
I held a 6 pound baby last week and realized that my baby is awfully big these days. He certainly thinks he's a big boy.
