oh I could so be stricter with dd1. But, tbh, I don't want my home/family life to revolve around issues. She eats arange of things, and gets a reasonable balance. That does it for me.
re: the engaging with food, dd1's school do an awful lot of playing with food.
So, crumbling biscuits to see the texture change, dropping jelly cubes into water to see the splash/see how slippery they get (and note the colour change of water, mash up banana and make patterns with a fork, pouring custard from jug to jug, playing with lentils.dries peas
I think the idea is to take all the emphasis away form eating - it's all about play. so the children are not stressed about it, as not expected ot eat it, but if they fancy popping the odd bit in (MUST BE VOLUNTARY) then no worries, but don't even suggest it. this way, the children get more used to the different feel and smell of the foods (dd1 is particularly smell averse), and so it isn't such an assault when it comes to meal times.
will try to remember what other food games they play - I know they "milked" a cow (used a rubber glove for the udders, attavhed to the bottom of a cut out cow) and then drank some milk (rice milk for dd1)
They also do paiting with fruit/veg, not just potato prints, but onion prints, and we had a blackberry painting the other day too. they did something with garlic the other week too.
on the engaging with food front - when you start to think about it, the possibilities are endless - moving from plate to plate (even if it is moving it off their plate onto yours - you can then model how yummy it is) or feedign to teddy/you/the dog
dd1 used to insist on feeding something new to daddy (presumably to check it wasn't poisoned ) before she would try some, but hey if it works, it works! (sadly, she is far more suspicious these days)
