My 17 month old DS is a NIGHMARE with food. He has a big brother and sister (6&4) who are brilliant healthy eaters but he is a real worry.
I always cooked fresh food for my first two and they got the odd commercial baby food, Usually Plum, on the run. They both ate well and still do. Will try stuff and eat fruit like it's a treat 
.
Number 3 came along and I have moved to the sticks. The only decent (or what I thought was decent) baby food was Ella Pouches.
So I fed him with a mixture of home made and Ella. He quickly became very fond of Ella and started refusing all of my food. I was so fed up cooking big batches of baby food that I eventually was feeding him mostly Ella. The only thing he'd eat of mine was a tomato based stew but in hindsight it was because it would have sweetness with the tomatoes and sweet potato.
I talked to my friend about it and she said her DD was the same. She fed her DS on a mixture before Ella was around then her DD had both home cooked and Ella and became so fond of them she'd only eat Ella. She still doesn't eat at 2.5. She listed what she will eat (not much) and like DS, it has to be sweet.
I have since spoke to a further 3 mums who have found the same. Ella pouches resulting in children who won't eat anything except sweet. One mum told me she recently read something about how Ella make all of their food purposely sweet and this was resulting in eating issues in children.
I haven't seen this article myself but it is obviously true.
So, My DS will eat Porridge - only if drowned in honey. A small selection of fruit. Tomato based pureed food. Spaghetti Bolognaise. Toast. Pizza.
He is terrified of food that isn't on the list above. So Pasta, meat of any origin, fish, sandwiches, cheese, any vegetables (except sweetcorn), rice, soup and basically any normal solid food.
He gets hysterical if anything other than the small list given is placed in front of him. I never force him as I don't want to scare him further. Sometimes I gently show him by me taking a bite then put it to his lips. He clamps his lips together then comes forward letting his lips quickly touch the said food then jumps back in horror - utter horror.
The kids try to encourage and feed him but no.
I have taken him off formula as I was giving him this just because of the added vitamins etc but was hoping he'd eventually start trying foods himself. He only gets a wee cup of milk with his breakfast and a bottle at night (although I know he shouldn't by now).
He is also the most poorly child I have had. He shakes nothing and has started yet another bad cough. The other two have always been well so it just shows what a difference good food makes.
What drives me absolutely nuts is, if the kids come back from a party with party bags full of chocolate, sweets, cakes - He is on it!! Oh yes, he'd try any crap if given half the chance - how the hell does he know?? I don't feed him any chocolate of biscuits but he is willing to eat any of that.
Anyone been through similar and came to the other side?
