Teddy is absolutely precious. Congratulations on your new little boy
Gemy gave you excellent advice, I would follow her suggestions.
As far as him seeming to be uneasy and flattening himself to the ground when you went to pick him up, it may not mean anything. Belle has been with me since February and she still sometimes does that when I bend down to pick her up. She reacts better if I get down to my knees first to pick her up.
