I am trying to be more consistent with mealtimes in order to combat Nat's eating issues. So the plan is something like this (even though the reality some days is different):

Dinner @ 5:30-6pm
TV off
We sit at the table, hold hands and say grace (Natty usually says it - is very cute! And Phoebe is only now beginning to want to participate by holding our hands)
I choose what goes on the plate and what time we eat, the children choose whether they eat and how much
Natalie is to ask politely to leave the table once she is finished

Sometimes I cave in and allow them to watch TV during dinner (generally if I've had a shocking day/afternoon and want to be on BB while they are otherwise occupied) but I am trying not to do this too often.
I try to limit afternoon snacks from about 4pm (I often start cooking dinner around 4:30 anyway), the only exception to this is when Phoebe hangs off me while I'm trying to cook, I will generally fling her a few Sultana Bran Buds to carry her through the harrowing time of waiting for her dinner
