Those that give up after the first attempt have themselves to blame. Your intention of trying to give your child a healthy nutrition is a step in the right direction. You will need a little patience though. Generally, children around the age of three develop certain scepticism towards new and different foods. If smell or consistency seem suspicious, the little ones are capable of previously unknown strengths of rejection. Even in these scenarios the family chefs should not be offended nor intimidated. The resistance can probably be softened by repetitively presenting a certain ingredient to your child.
It is nonetheless very important NOT to force your child to eat anything he doesn't like. Just trying a little bit of a new food is enough at this stage. This struggle with vegetables need not happen 7 days a week. But some meals, especially the ones you are convinced off, should continuously reappear on the dinner table. Experts offer the magic number 17, i.e. the maximum number of times before even the strongest rebel will start loving a food. The accuracy is questionable, but the idea is there, give yourself and your child plenty of attempts at certain foods. The thinking human can change his mind – even the littlest one.
