I don't know whether I should be worried about DS's eating.
DS is almost 3.8 and at a school nursery which he loves. Until he was 3, he was at home with me so any food issues that he has must stem from home.
He will usually eat: cheese sandwich, marmite sandwich, cheese alone, ham alone, juice, water, crackers, innocent smoothie, banana, apple, organix baby snacks, chocolate and mcD chips (nothing else from mcD), toast and marmite
He will sometimes eat: milk, yoghurt, grapes, cucumber, carrot (raw), cake
He has been offered a hot meal at school every single day this term (and last term). He has been allowed to play with this food and is deliberately sat between 2 children who are very good eaters. He has refused EVERY SINGLE meal ! They will give him a piece of cheese/piece of dry bread/fruit and he will eat this for lunch.
Today is typical, he's had crackers with butter and marmite for his tea and some milk. Quite a large quantity of crackers.
He seems to be healthy and his speech is normal/average for his age. He is very tall and skinny and I have never seen a 3yo with soooo much energy. Nothing will knacker him out and he has not slept in the day since he was a baby. He will do 5 full days at nursery school, love every minute of it and participate fully. However, he will still go to bed at 9pm (at least). He has a few minor ASD traits, but they are so minor that I have been told if he needs a diagnosis, it will not be given for at least 4 years because is is mild. (We have aspergers in the family so I am quite familiar with it). It does not seem to be causing him issues at nursery, although the staff are aware of it and make a special effort to ensure he is not left behind or isolated.
When he was a baby, I breastfed him til he was 13m. During this time, he ate any food that was offered to him, not fussy at all. He still ate most things until he was about 15-17m and then started refusing stuff. He drank cows milk from 12-16m but then refused it - only in the last couple of months have we been able to reintroduce it.
I also have a DD who is 19m. She eats anything and everything. Occasionally she will spit something out if she doesn't like the taste. Often DS will be sitting at the table with DD and he will put his food onto DD's highchair. She will happily eat it, but I do watch out as I want to know what he has actually eaten.
Regarding his intake of chocolate and chips, these are very limited and he is not holding out for them to be offered. Recently, we deliberately went 2 months with all choc and chips totally banned for him (he didn't know about it, he never saw any) and it did not make any difference to the amount of proper food he consumed (small). He will regularly refuse breakfast and lunch and then eat a lot of crackers with butter and marmite in the afternoon. If he refuses a meal, it doesn't affect him at all.
Would you seek help it this was your child and if so, where would you get the help from? I am worried that it was something I did and I am worried about DD starting to not eat as well. Additionally, I know toddlers can be extremely fussy, but where does it end? At what age must they start eating properly?
