He LOVES eating. All the time. In fact, he is so impatient when it comes to eating. In between every bite, he basically yells at me. He also can't stand it when we're eating and he's not, even if I just fed him. So, we give him whatever we have. Once, it happened to be a pickle. He didn't seem to mind at all.
He also loves the bath/shower. Recently, I realized that it was much easier to just bring him in the shower with me than trying to shower while he was napping (since that usually wakes him up for some reason). I found out that he loves it and so does double duty in letting me shower and keeping him very happy. Also, I've come up with a system where after I get out, I fill up the bath and let him play while I get ready. It works great! I think his favorite thing to do is pull everything off of the side, into the tub, and then splash a lot.
Steven loves making a clicking sound. Every time he's unhappy and I make that sounds, he smiles so big and gives me this look like, "finally! you're speaking my language" and then he always makes the sound back to me. In fact, I was watching this video on my phone earlier and he heard himself making the noise, and so from the back seat of the car, he started clicking too :)
Last of all, Steven loves being read to! He especially loves it when TJ reads because he does it in a much more entertaining way than I do...
