Cook two meals? Why?
Cook yourself something and let DP do the catering for his kids. Lets see how long he can keep that up!
My own kids were given nice food, freshly cooked snd we all sat down together. we had the eat it or have nothing rule and made the odd mistake where we realised later that toothache, illness etc were a factor. Or they genuinely did not like it.
My son still doesn't like lamb!
But they will now try anything and have much wider tastes than I do, never leave a scrap on their plate when they visit.
My current partners kids are a different story. As their mum was run ragged just getting them to and from school and activities and working full time they had very different eating habits.
Tv on during every meal, a lot of pasta with either just cheese or a tomato sauce, baked beans a frequent filler. Chocolate after every meal.
Came as quite a shock to me, and we decided we would tackle it bit by bit.
Tv off was easy enough. Just keep repeating yourself. Sitting at a table together without one of them just getting up and wandering off took a bit longer.
Eating the same food was the hardest, just broadening their palate was a challenge. I'm no gourmet, just fairly traditional dinner dishes my mum made and some Indian, thai and Chinese things I can do added to the menu.
They still eat rubbish at their dads. Ready meals, pizza, take away and some badly cooked stuff! Can't blame him for trying!
But now they openly say how much they enjoy the food when they're with us. The youngest has even been asking for fish curry this week, for a boy who wouldn't eat anything a cpl years ago that's quite something.
My tip would be if you're going to give them something new, give them a very small amount before stuff you know they'll eat. Have just the main dish yourself and ask them to try it, they can have something else when it's finished. And don't take no or tantrums.
Gradually increase the amounts until the old stuff is a side dish, then drop it.
Every now and then, once a week maybe, give them something off the old menu. Ours stopped asking I can't remember the last time I had to eat a chicken Kiev!
No magic bullet, they don't pile sugar on cereal any more but I can't wean them off Nutella or cocoa pops! And they still leave the last mouthful of food on a plate or in a dish!
Can't win em all!!
