We finally got around to purchasing a bathtub for Jack, making it easier on our backs. The past week and a half we have gotten into a routine of giving him a bath before bed. I think it has helped alleviate the long crying fits in the evening. We have him in the sling, but I think he will be outgrowing that in a couple of weeks since he is about 13 lbs. He mostly enjoys it, though he holds onto Ryan's fingers tightly.
