18 month old v v v fussy eater HELP ME!

[Wigglesworth]

My 18 month old DS and his eating habits are driving me insane. He has been a fussy eater from about 9 months old and has gradually narrowed down what he will eat to a very small menu. He always eats his cereal, nibbles at his toast, he will eat corned beef hash, cod fish cakes, jacket potato with tuna mayo, and hummus with bagels dipped in.
I have tried him with literally every food type I can think of, he won't touch pasta, anything tomato based, meat (other than corned beef hash), most vegetables, most fruit. Although he has absolutely no trouble finishing off his yoghurt.
I have tried not giving him a pudding if he doesn't eat any of his main meal, a change of setting, a new table and chairs instead of a high chair, new plates and knife and fork, letting him feed himself, me feeding him, multitudes of finger foods and even eating in front of the TV .
I am becoming increasingly frustrated and worried about him, he is quite skinny (he still wears aged 6-9 month old jeans) and he was average weight when he was born. Even the nurse that gave him his MMR last week remarked on his skinnyness. I haven't had him weighed for a while and TBH last time I went the HV just told me it's a phase.
He has been like this for months, he eats ok for a week or two then goes back to eating very little and there is only so much you can blame on teething and colds TBH.
Do you think I should take him to the GP or am I wasting my time? Any advice much appreciated.

if its any consilation my ds is 20 months old and is exactly the same. it is definately a phase thing because my nephews did the same thing. they all of a sudden start asking to try new foods. have you tried giving him larger portions of the food you know he will eat? good luck

Is he generally healthy and active? If so, I wouldn't worry too much (although I have in the past). My DD has only certain things she likes. They're reasonably healthy and from the range of food groups, so I try not to stress tomuch. My MIL who raised 5 healthy children recently told me not to worry too much as long as she eats at this stage. She says the teenage years were when she turned into a dictator, as she believes bad habits are formed then. It made me feel better.

Have you tried soups for getting him to eat vegetables? Just an idea. My DD will push a pea round her plate for hours but will wolf down practically any vegetables I give her in the form of soup. IT's good for doing meals that you ahd DH can eat too.

Our faves that you might not have thought of are:
carrot, courgette, celery and lentil. Chop or grate in the food processor slightly more carrots than courgettes, and less celery than courgettes. Soften for a good long while in oil and butter. Wash and add a handful or two of red lentils and some stock and a big ripe tomato (I find the Boots stock very expensive but the best one I have found of all for cube-type stock). Boil for 30-40 minutes. Blitz for baby.

swede, onion, bacon and cabbage.
Gently sweat down swede, onion and bacon chopped (about four rashers of bacon to one medium swede and onion). When softish, boil with stock. At this point I blitz and give to DD. For DH and I, I shred cabbage and simmer in the soup until soft.
