I have five and they all loved playing with the cords to lamps or the cable that was hooked to the tv. Overall parenting is about consistency, on any issue that you want enforced, it will become tiring but keep moving your son away from the cords and tell him No! Our second son once wrapped the cord around his neck, luckily I came up on him within seconds of him doing it, so they can be dangerous. I wouldn't buy the cords and attach them to anything, that will only confuse him. When we bought our children toys a lot of times the age range was higher than what age the child was (not by more than a year), we tried to find things that interested them. Try finding something that is a station type play, ie push toy or play yard, instead of a small single toy. Our twins were 9 months when we bought the see through blocks and they have different things inside the blocks (Fisher Price), they also sell a wagon that lights up and makes music that the blocks go in, the twins loved it and it kept them busy from 10- 20 minutes at a time,which is long for their age!! :) My friends daughter has the same blocks but with a hippo (I think) push toy and it picks the blocks up! Anyway, I wish you the best and it is normal for your son to be doing this but you just have to remove him from temptation, which will be the story of his life! LOL! Good luck!
