When your child eats little and tosses and turns at night

What follows combines several patients' visits into one composite story. It is not about any one child, and anything that could identify someone has been removed.

How do children usually come to us?

Parents tell us their child is a small eater who can't finish a meal, and puts the spoon down after just a few bites, saying they're full.

They also mention that the child has trouble falling asleep and tosses and turns for a long time. Many mornings, even after being woken up, the child doesn't seem refreshed.

Parents are often worn out from trying to get their child to eat. In the exam room, we listen to that story first.

Why look at eating and sleeping together?

The energy a body uses to grow comes from eating well and sleeping well. If one of the two breaks down, the other can't hold up for long.

When food isn't digested comfortably, the belly feels uncomfortable, and an uncomfortable belly makes sleep shallow. Shallow sleep means little appetite the next day. This loop has to be broken first.

So rather than asking "What else should we feed this child?", we first ask, "Is this child's body able to use what they eat right now?"

What do we look at?

We gently press on the belly. We check where it feels firm and how the child reacts when we press. We also measure body composition.

We measure body composition at the start to create a baseline for later comparison. Just looking at a child, it's hard to tell what has changed.

We also write down exactly how the day goes. We ask what time the child goes to bed and gets up, what they do before bed, and when they have snacks.

How do we treat it?

We use herbal medicine to build up digestive strength and settle the belly. The aim is not to force the child to eat more.

At the same time, there are things we decide together with the parents: keeping mealtimes regular, no screens before bed, and moving bedtime earlier. These three.

This isn't something the child is told to do. It's about changing the family's daily rhythm together, so we say clearly that this part is the parents' job.

How did things go?

The first thing that changes is the mood at mealtimes. There are more days when the child picks up the spoon on their own, and after that, the time it takes to fall asleep gets shorter.

Height and weight come after that. So for the first few weeks, we look together not at "How much have they grown?" but at "How are eating and sleeping going?"

What are the limits of this approach?

We don't tell you how much taller your child will grow with this treatment. What we do is create the conditions in which growth can happen.

If your child is losing weight, has a fever that lasts a long time, has trouble swallowing, or often vomits after eating, see a pediatrician first.

To parents with the same worry

  1. Not eating and not sleeping keep feeding each other.
  2. Before "What else should we feed them?", we ask "Can their body use what they eat?"
  3. Measuring body composition at the start gives you a baseline to compare against later.
  4. Mealtimes, screens, bedtime — it's about changing the family's rhythm together.
  5. If your child is losing weight or has a lasting fever, see a pediatrician first.

We start by checking where your child is right now. We won't rush you; we'll tell you, based on evidence, whether it's fine to wait or not.

If you're not sure whether to wait or to act now, come see us once. We'll check where your child is right now, and we won't rush you.

Every child grows at a different pace, so the same treatment can lead to different courses.

Have symptoms on your mind?

We're open until 8:30 p.m. on weekdays, and on weekends and public holidays too.

I see patients whose tests came back normal but who still don't feel right. I check the state of the body through abdominal diagnosis (pressing on the belly), tongue diagnosis and pulse diagnosis, and I record what I find as numbers so we can compare at the next visit. With pain, I don't look only at the spot that hurts. I look for the cause in the way your feet meet the ground, the balance of your jaw and the way you walk. When I explain a treatment plan, I also tell you which study, in which journal, it's based on. I believe evidence only counts as evidence if you can check it yourself.
