Can Kids Drink Decaf Coffee or Tea?

ByI Love Decaf

Can kids drink decaf coffee or tea? For older children and teenagers, an occasional small decaf contains far less caffeine than a normal coffee. For babies and young children, NHS guidance says caffeine is not suitable, so water, milk or naturally caffeine-free drinks are the better route.

The useful bit is not whether a drink has the word decaf on the packet. It is how much caffeine is actually in the cup, how old the child is and whether caffeine already appears elsewhere in their day.

The short answer for parents

Decaf coffee and decaf tea are low caffeine drinks. They are not always completely caffeine free.

For babies and young children, NHS guidance is straightforward: caffeine is not suitable. There is no nutritional reason to introduce coffee or ordinary tea early, decaf or otherwise.

For older children and teenagers, the caffeine in a small decaf is much lower than in regular coffee or tea. European Food Safety Authority guidance also gives parents a useful way to think about total caffeine intake, but it should be treated as a safety assessment rather than a target to aim for.

How much caffeine is in decaf coffee?

A brewed cup of decaf coffee can contain roughly 2 to 15 mg of caffeine depending on the coffee, the amount used and the brewing method. Most of the caffeine has gone, but not every last molecule has packed its tiny suitcase.

For context, approximate caffeine figures used by EFSA include:

  • Filter coffee, 200 ml: around 90 mg
  • Black tea, 220 ml: around 50 mg
  • Cola, 355 ml: around 40 mg
  • Decaf coffee: usually a small fraction of a regular coffee, often only a few milligrams
  • Rooibos, peppermint and many fruit or herbal infusions: 0 mg if the blend contains no caffeinated ingredients

Serving sizes and recipes vary, so these are comparisons rather than promises about a particular mug.

What UK and European guidance says

NHS guidance says caffeine is not suitable for babies or young children.

For children and adolescents more broadly, EFSA concluded that daily caffeine intake up to 3 mg per kg of body weight does not raise safety concerns. This is not a recommended daily allowance. It is a level used in EFSA’s safety assessment.

EFSA also notes that around 1.5 mg per kg may affect how quickly some children and teenagers fall asleep and how long they sleep, particularly when caffeine is consumed close to bedtime.

The sensible family rule is therefore simple. Keep caffeine low, remember that decaf still contains a little and do not assume a decaf drink is automatically irrelevant if a child is particularly sensitive to caffeine or already struggling with sleep.

What should younger children drink instead?

For young children, water and milk remain the everyday choices recommended by the NHS.

If the attraction is the ritual of having a warm drink with everyone else, a naturally caffeine-free option can make more sense than coffee. Rooibos, peppermint and many fruit infusions contain no caffeine naturally, provided the blend has not had tea, coffee, guarana, yerba maté or another caffeinated ingredient added.

Serve drinks at a safe temperature and check the ingredients. “Herbal” is a useful category name, not a magic forcefield around every possible ingredient.

Decaf tea, herbal tea and rooibos are different things

Decaf tea starts as tea. Most of its caffeine is then removed, so a small residual amount can remain.

Rooibos and many herbal or fruit infusions never contained caffeine in the first place. They are naturally caffeine free.

This distinction matters if the goal is genuinely zero caffeine. A decaf brew is very low caffeine. A suitable caffeine-free infusion is zero caffeine.

Is decaf coffee safe for kids?

For babies and young children, NHS guidance says caffeine is not suitable. For older children and teenagers, a small decaf is a much lower caffeine exposure than regular coffee, but age, body size, total daily caffeine and individual sensitivity still matter.

There is no single UK age at which coffee suddenly becomes a recommended children’s drink. If an older child or teenager occasionally wants decaf, keep the portion sensible and remember the small amount of caffeine still counts alongside tea, cola, chocolate and other sources.

If your child has a medical condition, takes medication or reacts strongly to caffeine, ask a GP, pharmacist or another qualified health professional for individual advice.

Can kids drink decaf coffee before bed?

Decaf is a better caffeine choice than regular coffee, but it is not necessarily caffeine free.

Because caffeine can affect sleep in some children and teenagers, a naturally caffeine-free drink is the simpler option close to bedtime, especially if sleep is already a battle of wills involving six glasses of water and an urgent need to discuss dinosaurs.

Is decaf completely caffeine free?

Usually, no. Decaf means that most of the caffeine has been removed.

The amount left in the cup varies with the coffee and the way it is brewed. If zero caffeine is the goal, choose a naturally caffeine-free drink and check the ingredient list.

What about cola, chocolate and energy drinks?

Coffee is only one part of the caffeine picture.

Cola, chocolate, tea and energy drinks can all add caffeine to the day. A parent looking at total intake should consider all of them rather than focusing on the occasional sip of decaf.

The bigger practical win is keeping high-caffeine drinks away from children and avoiding a pile-up of caffeine from several different sources.

The bottom line

Decaf coffee and tea contain much less caffeine than their regular versions but they are not always caffeine free.

For babies and young children, follow NHS guidance and keep caffeine off the menu. For older children and teenagers, an occasional small decaf is a low caffeine option, but total intake and individual sensitivity still matter.

If the goal is simply to join in with a warm drink, naturally caffeine-free rooibos, peppermint or fruit infusions keep the arithmetic out of it.
