The last time I was able to put Chewie on this scale. Taken on March 1, 2016, and allowing for his wiggling we got his weight at 10 lbs 12 oz.
These were taken today, March 15, 2016. He has had his first vet visit now - last week where he was 13 lbs 8 oz - and we estimate him closing in on 20 lbs.
We still all adore him. (Except for Yoda and Simba, the former not being interested and the latter deeply suspicious of his intentions.) Especially Leia who watches out for him and comes to us any time he is whining in his kennel. We started covering his kennel because the heater vent would blow on him and wake him and Leia has repeatedly removed the blanket so she can make sure baby is okay. They play together all day long. Chase, keep away, tug of war, and especially wrestle.
He can sleep through the night, but he isn't doing it on a regular basis. Unfortunately. And he likes to get up and beg for breakfast between 4 am and 6 am. During the day he really likes to curl up and nap on Carus's bed while she is doing school work.
Potty training is going well... for the most part. I can be in charge and he won't have a single accident and then I put someone else in charge and 5 seconds later he has piddled on the floor. While at work the other day he peed on my pillow on Robert's watch. His cues aren't always in a timely manner - he has peed while whining to be let out in the same second several times. But he is only 9 weeks old so I'm not expecting the world.
In related news, Robert and I are going to buy a carpet shampooer.
