FROM “I’LL EAT ANYTHING!” TO “I DON’T LIKE IT!”
When your child suddenly stops eating — should you worry?
One day your child is happily eating everything you put in front of them. The next, they refuse their favourite meal, push away vegetables and announce that they “don’t like” foods they used to love.
Sound familiar?
Sudden changes in eating habits are common in children, particularly during the toddler and preschool years. As children grow, their appetite can naturally fluctuate, and becoming more independent can also mean becoming more opinionated about food.
But sometimes, a sudden change in eating can have another reason.
Why might a child suddenly eat less?
A reduced appetite can happen with something as simple as a minor illness, constipation, tiredness or a change in routine. Teething, mouth ulcers, sore throats or other discomfort can also make eating less appealing.
For some children, texture, smell, appearance or sensory sensitivity can play a role. Emotional changes, anxiety or stressful events can also affect appetite.
So, should you worry?
Not necessarily. If your child is otherwise active, well and growing normally, occasional fussy eating or days of eating less are usually not a reason for panic.
Try to avoid turning mealtimes into a battle. Offer regular meals and snacks, provide a variety of nutritious foods, and allow your child to decide how much they eat. Keep mealtimes relaxed and remember that children may need to be offered a food many times before accepting it.
When should you speak to your paediatrician?
A persistent or significant change in eating deserves attention if your child:
* Is losing weight or not growing as expected
* Has very limited foods or is becoming increasingly restrictive
* Frequently gags, chokes or struggles with certain textures
* Seems to have pain when eating
* Has ongoing vomiting, diarrhoea or constipation
* Has noticeably reduced energy or seems unwell
* Refuses most foods or fluids for a prolonged period
The key is to look at the whole child — not just what is on the plate.
A picky phase can be completely normal, but a sudden and persistent change in eating is worth discussing with your paediatrician, especially when accompanied by other symptoms.
