When do Your Kids Start Keeping Kosher?

My son is approaching 1 year and we are getting ready to switch him to regular milk. How do you deal with the kosher aspects of it?

If I serve a meat meal, do you give milk either before or after? Do you serve it with the meal? If so, how do you wash the cups/utensils?

We have the added challenge of my son having a high chair that sits at the table . We have a Stokke Tripp Trapp which I love (http://www.stokkeusa.com/tripptrapphome.htm) and have meat/dairy mats (http://www.kiddopotamus.com/p_tiny.php) on the table. This basically means that it would be easy for him to throw meat or milk onto the regular table and have it splash/mix with the rest of the stuff. Do you give them water at meals then and milk after?

When do you start having them wait between milk and meet? 3?

Just curious what you all do.

Thanks for the help.
