HI L.,
I can totally understand, we did the same thing back and forth and eventually just got rid of the high chair!! My 21 month old sits at an adult chair, and does get up a lot, but I finally decided I don't really mind because he always comes back to eat(although sometimes we tell him the cat is going to eat his food if he doesn't which seems to work, not the best idea though). However it seems like you really want her to sit, so I agree with the others to make it really clear that it is either the big chair or the high chair.. I wouldn't have her at the table until the food is right at the table ready for her,so she has less time sitting. Also, I don't think it is realistic to expect a 2 year old to sit until the rest of the family is done eating, unless it only takes 10-15minutes for everyone to eat or unless your at a restaurant. I would suggest you enforce it until she eats what you believe is a reasonable amount then let the girl go play. Good luck. Hope is gets better soon.
