Joining in Ohio....I have a 3 yr old who is a terrible resistant eater. He has textural and temperature issues around food too. It's a struggle because DH and I love food. Our second LO seems to eat everything and makes up for his brothers fussiness but also makes meal times just so frustrating.
Brummum we have tried a number of things with Z. Our main issue is he is totally unmotivated by food. He will also happily eat nothing but then moan all day long
we're waiting on a OT appointment as he has anxieties which I don't think is normal fussiness but for now I try to offer him mostly safe foods and encourage touching, licking, playing, kissing, biting and spitting new foods. He often refuses foods I know he does like, and I do not offer anything else in these cases. Ie I know he likes marmite sandwiches. If I make some for lunch and he wants 'something else' then until he has had his sandwiches he doesn't get something else. That said I try to offer 3/4 choices 2 of which I know he likes and 1 is not a completely new food. If he has a good go at it he can have something else. I never force him to try new foods but I just keep exposing him.
Sorry, not much help as he's just really really silly about food. The usual things don't seem to work for us.
I will say in the times I have lost the plot and made a battle out of food....it never ends well and we usually regress.
