Sorry to continue to point this out, but I'm getting seriously tired of arguing against straw men.Is bread nutrient dense? No, but it's better than nothing, and it is a very inexpensive source of quickly digestible calories.
This child isn't suffering from poverty or having nothing to eat. You're not arguing the facts at hand.
More straw men. The child is not a world class triathlete.If you are a world-class triathlete, you're probably not going to get very far eating purely paleo and you're going to have to supplement with at the very least rice, benign flours (yucca/cassava/tapioca, potato starch, arrowroot) and refined sugars to get the calories you need to perform. For a growing child, some added glucose may be highly beneficial - moreso than added fats. I don't consume bread because I rarely ever see the point, but if I were it doesn't make me a sinner.
Are you serious right now?It's irresponsible to raise your children on a diet of unhealthy, processed foods. It's potentially worse to raise them in an environment of fear to eat a sandwich.
OH MY GOD, ALL OF THIS AND YOU AGREE WITH ME!A 21 month old does not need bread. They have no longterm memory and will forget it quickly. You can easily give them fruit, potatoes and the the like with no harm. This is the perfect opportunity to remove the child's association with bread so they don't grow up addicted in some way. However, when they get older, the more control you try and place the further you'll push them away.
