I tried to be creative like you with the lunches. Now my son won't eat his lunch at daycare because it's not a smiley face. Daycare told me he cried yesterday and they didn't understand why he was so upset. They didn't know what the smiley face meant (with the grapes and carrots and star sandwiches). So today I printed out the picture I took and gave it to the teachers so they could arrange it for him.
You didn't tell me that once you start having fun with the lunches that you have to keep it up forever- LOL-!!!
