I cannot seem to hold DS's attention for more than a couple of minutes at a time before he decides to crawl off and do his own thing.e.g. play with the fridge magnetes,PAT the cat!.Even when I try to join in these games DS looses interest quickly and goes onto something else.When he is in his play pen he plays quietly with his toys but as soon as I let him out He is off (he is not caged up a lot).Is it me that is just too boring for him,should I be trying to make games more exciting(HOW?) or is DS just a normal crawler and I should just butt out?
