I have a kids table in the kitchen plus up to three highchairs. Our dining room is our upstairs playroom and big kid nap room, our eating table for family is actually in the end of the family room which is a really big room. Just off the kitchen and works well since it is just hubby and me and special needs child so we sit and eat and watch the news from there.

They are in chairs till about 18 months but a lot has to do with size, ability - ie we try to use utensils at the table not just fingers so they need to have had lots of practice and not be overly messy since there is no tray at the table. Mostly they stay in the high chairs till I need it for the next child coming in and we are making transitions all around ie playpen to nap mat, highchair to table.
