Thanks so much again ladies - some really great points here.
What works with J with other stuff is time, consistency, distraction and ignoring bad behaviour and praising good. So a great point Claire - I just need to work out how to apply a lot of this to Jacob's eating as I guess the main difference here is that he genuinely is in control whereas with other things I still have a degree of parental control iyswim?
Thanks for the hugs Charli - food battles are tough - but we did genuinely abandon them quite a while ago and very much do the 'if he eats it fine, otherwise out' approach - but still he seems to find something to fight us over.
Mashi - I've often though of a GW type approach but never really done it. I need to work out what food type I am trying to turn into what first - but yes - I'm sure that might work. I would be happier if the jam was on wholegrain toast, not white for example.
Thank-you for posting Fiona - it really does help a lot to hear that there are other out there who struggle as well. I know that sounds wrong - but often I feel like we are the only ones iyswim? I do need to put some effort back in - that is also part of my issue - that I got fed up of it and stopped making and trying.
Shiv - I think the 30 min rule is sensible and that is what I think we will aim too. I think I can otherwise distract him until a meal or snack time as long as we can go out and do something. I mean - he can always have a nice drink instead

.
Would J try new things if I asked? No - I don't think so - he would just say nah nah and cry and shake his head. But he will handle new foods during food preparation as he loves messing about with stuff like that - and he will often try if no-one is looking. He will also help himelf to things off other peoples plates sometimes - other times he will play about with a fork in it but never eat - but I guess this is OK at this stage as well?
DH agrees no comments over the eating as well so I think that may help

But what should we do if he signs and says yum yum? Agree with him or ignore that as well? He often does that with a meal that he then doesn't eat - very odd!!
The other thing he will do is talk and sign about his meal while eating it - so might say 'no no sausages' and 'no no cake' - which means 'it isn't sausages or cake'. I usually join in this conversation as it doesn't seem to have any bearing on whether he eats it or not. Do you think that is OK? I mean - as long as it isn't commenting on HIM eating? The other thing he does is sign 'no no pigs' meaning his meal is not for piggies - he often runs through an entire flippin' farmyard before eating anything

. But again I sort of see this as just meal time converstion/ ritual with him and am thinking it is OK as long as again there are no comments on HIS eating?
Actually we took him out for dinner this lunchtime for the first time in MONTHS as I decided a late nap wouldn't kill him for once (and it hasn't but he hasn't handled it THAT well

). Anyway we all had sunday lunch stuff and he ate quite a bit - seemed to prefer it if he saw it come off somones plate thoug rather than the bits in front of him - but he had boiled potato, roast potato, turkey in gravy, a slice of carrot, a bite of yorkshire pudding, 2 bites of a stuffing ball that he helped himself too and declared 'ball' with delight, licked a bean then decided against it, and chewed a peice of sweetcorn and then spat it out. Not bad I though

- not enough to really fill him up though but a really great attempt. Kind of proves I really need to 'mix it up' though, doesn't it?
