More than just boobs.

Cassandra
My little guy is almost 12 weeks, he's a 34 weeker so I know that may factor in but when will I be more than boobs to him? When I'm home with him, which is 95% of the time he is either nursing or sleeping. I get a couple 15 min chunks where he'll let me hold him and chat but he won't let me put him down and I'm worried about his development. We do a little tummy time on my boppy in my lap, he's smiling and starting to coo but I'd really like to get him on the floor and working on rolling over, pushing up since those should be happening soon. Will he start to get more interested in what's going on around him soon?
