The main consideration is caffeine

Children are more sensitive to caffeine than adults because of body size, so caffeinated true tea affects them more per cup. That is the central reason tea for kids needs thought rather than a flat yes or no.

Caffeine free herbal is the gentle option

Well diluted, mild caffeine free infusions (such as rooibos or gentle fruit) are the usual sensible choice for children who want a warm drink, lacking caffeine and tannin, see herbal tea.

If they have normal tea

An occasional weak, milky cup is a long standing family norm in the UK; the sensible approach is weak, small, not late in the day, and not instead of water or milk, see the caffeine guide.

The iron and mealtime point

Strong tea with meals can reduce iron absorption, which matters more for growing children. Keep any true tea away from main meals and modest in strength, see tea and iron.

Sugar matters here too

Sweetened tea for children adds free sugars and dental exposure, and a sweet tea habit learned young tends to stick; if they have tea, unsweetened or barely sweetened is better, see sugar in tea.

Watch the herb, not just the label

"Herbal" is not automatically child safe; some herbs are potent. Stick to clearly child appropriate, well known mild infusions and check with a health visitor or pharmacist if unsure.

The clear takeaway

For kids: prefer mild caffeine free infusions well diluted, keep any true tea weak, small, early and unsweetened, away from meals, and ask a health visitor or pharmacist about anything beyond the obvious, see can children drink tea.

The essentials: Tea for children

Age	Sensible approach
Under 4	Avoid all caffeinated tea; herbal infusions in small amounts occasionally are usually fine
4-12	Small amounts of weak black tea fine for older children; main concerns are caffeine, sugar, and iron at meals
Teenagers (13+)	Caffeine tolerance similar to adults; the main concerns shift to sleep timing and caffeine load
Best children's teas	Caffeine free fruit infusions, gentle herbal (chamomile, weak peppermint), rooibos
Avoid for children	Strong black tea daily, sugary fruit teas marketed as healthy, any senna or stimulant laxative containing tea
Caffeine guidance	The NHS suggests under-16s keep caffeine low; an occasional cup of weak black tea is fine, not multiple daily cups
Sugar matters	Avoid sweetening children's tea heavily; the sugar habit set in childhood is hard to break later
Iron timing	If iron intake is a concern, time tea away from iron rich meals

If you do give them tea, what to choose

For caffeine free drinking, fruit infusions like Twinings Strawberry & Raspberry, gentle floral blends like Pukka Love and rooibos (no caffeine, no tannin) are the usual picks; chamomile is the classic calm option. For older children exploring black tea, brew English Breakfast shorter and weaker than adult style with extra milk. Avoid any "detox" or "slimming" teas marketed at adults; many contain senna and are not suitable for children. Browse the wider tea shop, and remember free UK delivery is over £35.

Herbs to be careful with for children

Most everyday infusions (chamomile, peppermint, rooibos, fruit blends) are fine for children in normal tea dose amounts. Go easy on liquorice root teas, which are best kept occasional rather than daily for children. Avoid "detox", "slimming" or laxative teas (senna, cascara, aloe) at any age. If a child is on medication or you are unsure about a particular herb, ask a pharmacist or health visitor first.
