S.S.
start putting some sort of white noise (a fan or low radio) in his room while he is sleeping. this will block a little outside noise. at his age he should still be having 2 naps a day. one in the morning and another one after lunch. get as much done as possible during those times. I will probably be the only poster to say this next line. Get a playpen / playyard a big sqaure one and fill it with toys. put it in the corner of the kitchen or somewhere you can see it and get him used to playing in it while your preparing dinner etc. I know lots of people don't like them. And I don't think putting a baby in one for hours and hours on end is a good thing. But being in one for half an hour while you do dishes is not a bad thing. he will be safe and you will have a little sanity left.
