We had the same and found that if we put DS in his cot with his mobile, he would settle down. We just walk up there every few minutes and wind it back up. He absolutely loves it now.

I have also sat him in his rocker with me in the kitchen while I cook or do the dishes. Sometimes it works great, other times not so great.

Our little man also absolutely loves Nickelback...I kid you not. His fav song is Animals. Some weekends we can sit him in the loungeroom with music on the TV.

We have just started to put him on his play mat, so he can lay there and watch everything above him (one of those rainforest play mats with the animals above them) He might only stay there for 5 minutes, but eventually he will get better and stay there for a bit longer. He was initially like this with his cot mobile.
