Sitting in big girl chairs.
We have graduated G. (right) and L. (left) to youth chairs for breakfast and lunch at the kitchen table. They are very cute sitting in their big girl chairs and so far they have done very well. L. has hopped down from the table a couple of times and has been quite disappointed that her meal was over. Since we don't allow children to get up from the table only to return a while later, we start this lesson early so it isn't an issue when they are older.
We were getting tired of dragging high chairs from room to room for each meal, so now the high chairs remain permanently in the dining room for the girls to use at dinner. This isn't because we don't think that they can manage sitting at the table, but because there really isn't any room for them. We seem to have a dining table crisis at the moment. Ours comfortably seats 8 and uncomfortably seats 10... 11 or 12? Not so much. At this point it seems easier to keep G. and L. in high chairs rather than figure out what to do with the table. I have a second table in the room that I add to the main table for when we have guests, but that seems a bit much for the one extra place we need. (Now, that is. When H. comes home we will need two extra places.) Unless a bigger table falls into our lap, I have a feeling that this will be our only choice. In the meantime, the high chairs are working well and the girls haven't really seemed to notice that they get to sit at the table in the kitchen, but not in the dining room. Or perhaps they do notice, but figure it's one of those oddities that they have no hopes of understanding.
