The one thing I won't do is make food a battleground. If he won't eat it - this is the alternative. (With an early bedtime as well, because quite frankly I needed the little treasure off, so I could (drink a large glass of wine) breathe. . .
I absolutely hate with a passion, making the kid sit at the table until it's eaten (cue tears, tantrums, and much gnashing of teach on both parties part), or serving it up on every meal until they eat it. I get to choose what gets put in front of the tube, the tube gets to choose what goes down it.
Oh, I also made a huge positive fuss of trying a new food, particularly involving grandparents, ringing them up to tell them what they'd done, with them primed to tell them what marvellous little beings they were, for being so adventurous and brave! (It was double points on the star chart). . .
I had one who was borderline foodphobic, would not eat finger foods, would not eat anything 'juicy', would not eat fruit. In fact, she existed on cheese, ham and marmite sandwiches for 3 months, for breakfast, lunch and tea. . . until she got bored, and went back to what she had been eating, which was a wide range of meat, veges, and a lesser range of fruit. Heh. Heh heh. . .
