WHAT has gotten into Avery?? He's not been housebroken very well yet, BUT he hasn't been doing what he did TWO times this evening!! Right in front of us he hiked his leg and wet all over the wall once and then the banister! I yelled NO! at him and hit my hand with a newspaper. He ran, but what has gotten into him??? He's almost eleven months old and isn't housebroken yet! How much longer???????
