First of all, there is no such thing as too much attention for any child. Taking a shower can be tricky if you do it when he is not sleeping. I had one of those bouncy seats that I put in the bathroom and put by kids in that while I showered. Then when they got bigger and didn't want to be in it as long I would take them out as soon as I was out of the shower and let them roam in the bathroom while I got ready. We keep a bottom drawer full of their toys and books so they have something to do besides pulling everything else out of the cabinets. You'll do fine, just find a safe place for you son and he'll be able to entertain himself while you shower. I also had the circular safety gate thing that I used with my first child once he was mobile. It gave him some room to play, but kept him safe while I couldn't see him.
