Most fussiness in young children is normal and passes. But there are specific signs that tell me a child needs proper assessment rather than reassurance, and I think parents should know what those are.
None of these mean something is seriously wrong. They mean it is worth a conversation.
Eating fewer than 20 foods in total
This is the clearest single marker. A typical eater accepts around 30 different foods or more across a week. A fussy eater sits at roughly 20 to 30. Below 20 total foods, I would want to look properly.
Count generously and honestly. Different types of bread count separately. Different cereals count separately. Add it up over a week rather than relying on your impression of a bad day.
Omitting whole food groups
If a child is not eating anything from the protein rich group, then I want to know where their iron is coming from, and that would be a problem.
In practice it is most often the vegetable group that gets omitted. A child will tend to eat a couple of fruits, though not always. Missing an entire group is a different situation from disliking several foods within it.
Growth or nutrient concerns that are hidden
Children can have very restricted diets and still grow fine, because they are getting enough calories and protein from the same foods they eat repeatedly. That is worth knowing, because normal growth can be falsely reassuring.
A child eating very few foods may still have an underlying nutrient deficiency, simply because they are not getting the full spectrum of what they need. That is exactly why assessment is recommended for a child eating a very restricted range.
Continually refusing nursery or school food
Some refusal when starting nursery is completely expected. Settling in takes time, and it is a big transition.
The red flag is when it continues and continues, and it cannot be explained by a normal settling in period or anything else you would expect. As a parent, if it is going on, it is unusual, and you are worried they are not having anything, then you would definitely need to get more support.
Gagging and vomiting that does not resolve
Gagging is very normal in the early stages of weaning, and very much to be expected. That is not what I am describing here.
If there is lots of gagging and lots of vomiting, and it is not resolving after a number of weeks, that is a red flag and worth looking into.
Being unable to self feed
If you are still finding that you have to feed your child, when you would expect them to be managing themselves, that is worth flagging.
Not coping around food with others
Some children struggle with food beyond their own plate. If your child is visibly disgusted by food, or has very strong reactions to other children eating, that is a sign that the difficulty is broader than preference.
Two things to rule out with your GP
It is worth seeing your GP if you have any concerns about constipation, or if you think your child is not getting enough iron.
Both matter here for a practical reason. If a child is constipated or has anaemia, it will affect their appetite further and make the whole situation worse. You can end up trying to solve a feeding problem when there is a physical cause underneath it.
What to bring with you
Keep a food diary. If you are really concerned about a child's eating, a diary does genuinely help to highlight what is going on, and it gives whoever you see something concrete to work from rather than a general description.
Where to get support
It is very individual, so always reach out for help if you are unsure about any of this. I am available through V&Me and do quick catch up calls with parents, whether you want to run something past me, you think it is a feeding difficulty, or you simply are not sure.
There is never a bad time to get support with your child's eating.
