Hi again,
To answer Spay's question. Our son was fearless and would laugh at anything. Now he is much more contemplative of surroundings and his language skills are exploding. I think that it is a combination of going thru a phase and as another poster said, perhaps some picked up tension in the household. Alex is continuing to do some serious sleeping and growing too. So perhaps it's a combination of everything.
Today I am trying to be much more relaxed, taking the advice of you all on these boards. Hubby is headed home with dinner and a bottle of wine.....
Edit: One theory--not to be sexist but are little girls more resiliant then little boys? My daughter has a core of iron. My son seems so much more fragile as I've observed in so many little boys, adopted or not.
