As an update, Ryker is 3 1/2 months old now and is starting to giggle and interact more. He loves being in his bouncer and is grabbing at the toys and actually bouncing rather than just wiggling around.
I don't have many pictures of him (bad Mommy), but here are a few.
I left Ryker sitting up in the corner of the couch and when I checked on him a minute later this is what I found. He was chewing on the toy. This is the first time I've seen him chew on anything except his tongue.
