Cockroach

My son is in to trying new foods and I couldn't be happier.  Tonight I made spaghetti for the kids and I was going to eat pot roast.  He told me he wanted to try my "cot roats".  My son has a very difficult speech problem we have been working on it for years.  And pot roast he just can't get out.  Every time he kept talking about  my "cot roats" It sounded like he was saying cockroach.  Gross!  Especially at dinner time.
