Why Picky Eaters Regress When Sick & How to Get Them Back on Track
If you have a picky eater at home, you may have noticed that when they get sick, their already limited diet shrinks even more. Foods they once tolerated may suddenly be off the table, and their willingness to try new foods can disappear entirely. This regression can be frustrating and concerning, but it's a common response to illness. Understanding why this happens and how to gently guide them back to their normal eating habits can make the process smoother for both you and your child.
Why Do Picky Eaters Regress When Sick?
Loss of Appetite – Illness often brings reduced appetite, which can be more pronounced in picky eaters. When they already eat selectively, a further decrease in interest can make mealtimes even trickier.
Sensory Sensitivities Heightened – Congestion, sore throat, nausea, or changes in taste and smell can make certain textures, temperatures, or flavours even less appealing than usual.
Comfort Food Reliance – When feeling unwell, children (and adults!) gravitate toward familiar, comforting foods. For picky eaters, this often means an even stronger attachment to their preferred, safe foods.
Negative Associations – If a child eats a food and then experiences vomiting, nausea, or discomfort during an illness, they may develop an aversion to that food, even after recovering.
Fatigue & Reduced Energy – Being sick is exhausting, and some kids may not have the energy to chew, swallow, or process new foods, leading them to reject anything that feels like too much effort.
How to Help Your Child Get Back on Track After Illness
Be Patient & Compassionate – Just like adults, kids need time to regain their full appetite and energy levels. Avoid pressure and allow their hunger cues to guide them.
Start with Familiar, Preferred Foods – Reintroduce foods they enjoyed before getting sick to rebuild confidence and comfort with eating. Stick to small portions and gradually increase variety.
Reintroduce Foods Slowly – If a previously accepted food is now being refused, try offering it in different forms (cut differently, mixed with a preferred food, or served with a familiar dip) to make it feel safe again.
Focus on Hydration – Dehydration can suppress appetite, so prioritize fluids like water, milk, smoothies, or broth-based soups before expecting solid intake to return to normal.
Offer Soft, Easy-to-Eat Foods – If your child had a sore throat or congestion, softer foods like yogurt, oatmeal, mashed potatoes, or scrambled eggs may be more appealing.
Encourage Gentle Food Exploration – If your child is resisting certain foods post-illness, allow them to interact with them in a low-pressure way (touching, smelling, or playing with them) before expecting them to eat.
Avoid Creating Power Struggles – While it’s tempting to push them back to their pre-illness eating habits quickly, forcing or bribing can lead to more resistance. Keep mealtimes relaxed.
Maintain a Mealtime Routine – Returning to normal eating patterns as soon as possible can help signal to your child that it's time to get back on track. Keep meal structure predictable without overwhelming them.
Model Enjoyment of Foods – Sit and eat with your child, showing enthusiasm for a variety of foods without putting pressure on them to eat the same things.
Give It Time – Regression after illness is normal, but with patience and a positive approach, your child will gradually return to their usual eating habits.
When to Seek Help
If your child’s eating doesn’t return to their usual baseline within a couple of weeks, or if their diet becomes even more restrictive long-term, it may be helpful to seek support from a feeding therapist, dietitian, or paediatrician. Picky eating setbacks due to illness can be challenging, but they don’t have to be permanent. With a gentle approach and plenty of patience, you can help your child regain their confidence in eating and continue expanding their diet over time.
