It didn't used to be that way. As a new mom, I read other blogs and talked to others about what they did at meal time. I thought up (what I thought were) exciting, nutritious breakfast and lunch combinations. I tried doing leftovers for lunch. Either way, those meals were greeted with whining--a habit we try not to welcome in our home. I was frustrated. I attempted the idea of offering a choice at breakfast or lunch to alleviate conflict. It wasn't working.
Finally, out of desperation, I just started giving them one option. The same option. Every day. I didn't argue. I just stated, "This is what's for lunch." Within a few days, the meal time dilemma was solved. There was no question in the girls' minds what we would be eating, and as a result, they never whined about not having such or thus. We have followed this routine for nearly 6 months, and to my amazement, they never complain, and they actually look forward to cereal and PBJ sandwiches.
