L.,
First, don't be embarassed - bed bugs are travelers and do not indicate that you are "unclean."
Second, my friend/neighbor had bedbugs, and I learned alot through helping her. I pray this is not what you have because they are very hard to eradicate (though it is possible!)
I wonder if you have bedbugs, because usually the whole house and all occupants are affected. One tell tale sign is three bites right in a row.
At first I thought you might have fleas, but then you said the dog was clean. Is there a possibility that there could be fleas where your son goes to daycare? Another possibility is scabies, which can be acquired through soil, animals, and many other sources. My son had scabies this year, and they were pretty easy to erradicate - I had to cover him in a lotion (permetherine). I hate to use the chemicals, but sometimes you just have to. My son also had lice (again, not a cleanliness issue) and the chemicals didn't work - I had to shave his head. WE have had lots of bug issues this year, and it has been a total drag!
I believe this is the email of a guy who has a whole bed bug website, and he will personally reply to your inquiries. It has been a while since I used it so I cant guarantee that this address is still good. <____@____.com>. This is his website: http://thebedbugresource.com/bedbugcontacts.htm
Good luck!!
