Yeah, Dale is 1 1/2 years old, and I am so looking towards that 2-3 year stage Could be b/c i have a 3 year old human child too, and between the two of them, they can really drive you up the wall! I have noticed Dale being more calm lately too, he only has another 6 months until he is 2...Swissies also, don't fully mature until 2-3 years...
