Today, December 5th, Arthur walked around the corner of the coffee table, looked at me, and said "Mama". Yesterday, the first thing he said when he woke up was "Mama". I'd say we have now reached the period where it is certainly a word he is saying with intent. He's being saying "mama" and "dada" and "baba" for awhile now, and I suspect the next word will be a "Papa" directed at Martin. There have been more communication advances in the past couple of weeks. After about 6 hours in his car seat (on the way home from Elliot Lake), Arthur discovered that he could make a wah-wah sound by hitting his hand against his mouth. He's been happily wah-wahing ever since. Another thing we noticed recently is that when he sees a cat, mostly, but it could also apply to a squirrel sighted out the window, he's replaced the reaching out he used to do with a "tsk-tsk". This is the sound we use to call the cats and he has obviously clued in to this being cute animal speak.
The tenth month has been a busy one for development as, not only is he communicating now, he's also taking the occasional step. Martin strongly believes Arthur will be walking in his tenth month, but there are only 6 more days for this to happen. Arthur loves run-crawling around the center post of our main room, especially if he is chasing or being chased. Today, he got a kick out of peeking around the corners to pretend to be scared by my roar-y sounds. Arthur still loves climbing the stairs and he's even experimenting with holding on to the rails on his way up. He's learned that it's safer to get off beds and the couches by turning around and climbing down backwards. Arthur gets very excited at the sight of a cup filled with liquid and gets agitated if he is not able to try to drink from the cup. We've been letting him try drinking by holding the cup for him. At the beginning he sucked in too much generally and coughed, but his technique has certainly transitioned from sucking to simply imbibing. Tonight, at supper, he was sitting on my lap while everybody was finishing their meals. He grabbed my glass and took control of tipping it into his mouth and taking a big drink. All of this development is, unfortunately, making him move a lot in his sleep which wakes both him and me.
Two teeth have arrived since the 9 month mark. Both his top and bottom lateral incisors on the right came in about a month ago. His hair is growing and starting to curl at the ends a bit. Sometimes it looks strawberry blonde and sometimes I'd call it auburn, but whatever the correct color is it is just quite pretty and soft.
I think we've officially entered the two nap a day era. This is a fine change as there's less of the day that Elsie needs to try to be quiet, however it does mean that I'm busier keeping up with him and monitoring the sibling interactions. Martin continues to take Arthur for morning walks around 7:30, and he will generally take a nap during this time.
