I've learned that Chase settles much better when he is lying on his stomach. At this age though, you would think that if he was laying on the sofa that nothing would happen as he wouldn't be moving around so much. HA! The other day I looked at him and he had turned 30 degrees from where he was originally positioned. Shocked the hell out of me! I also find that if I put him in one spot, somehow he manages to have moved up from this spot as far as he can go be it the edge of his bassinet or the arms of the sofa. He's been a toughie since day 1 with strong neck muscles (my other babies were the same), but I never expected him to be this tough.
