Quick answer

NHS guidance suggests introducing a cup from around 6 months, offering sips of water from an open cup or a free-flow cup without a valve, because sipping is better for developing teeth than sucking. Straw cups and 360 cups (which let a child drink from any point around the rim) can be handy at home and out and about. Aim to move away from bottles around your child’s first birthday. Many families use a mix: an open cup for practice at meals, and a spill-resistant cup for nappy bags and car journeys.

Why cups matter

Learning to drink from a cup is a skill, a bit like learning to use a spoon. NHS advice is to start offering a cup from around 6 months, when your baby begins solid foods. At this stage they will only take small sips of water with meals; milk remains their main drink.

The reason open and free-flow cups are recommended is simple: they encourage sipping rather than sucking. Long periods of sucking from a bottle or valved cup, particularly with anything other than water or milk, can be harder on teeth. Dental guidance also suggests keeping juice and sugary drinks to a minimum.

The main types of toddler cup

Open cups

A small, regular cup without a lid. It is messy at first but teaches the most natural drinking technique. Start with a tiny amount of water and expect spills.

Free-flow beakers (spouted, no valve)

These have a lid and spout, but water flows without sucking. They are a gentle step between a bottle and an open cup. Look for “free-flow” or “no valve” on the packaging if you are following NHS advice.

Valved “non-spill” sippy cups

These have a valve that stops leaks but means your child has to suck to drink. They are convenient for travel, but guidance generally prefers free-flow options for everyday use.

Straw cups

Your child sips through a straw. Straw drinking is a different mouth movement to sucking from a teat and many parents find it a useful skill. Weighted straws let a child drink even when the cup is tipped.

360 cups

These have a rim that seals until your child puts their lips on it and tips the cup, a bit like drinking from an open cup. They can be less messy than an open cup while encouraging a similar technique.

Product listings explain whether a cup is valved or free-flow. If you want to follow NHS advice closely, check this detail before you buy.

What to look for when choosing

1. Age suitability. The manufacturer’s age guide reflects spout or straw design and size.
2. Valve or free-flow. Free-flow is generally preferred for everyday drinking; valved cups are handy for travel.
3. Handles. Two handles help younger babies grip; older toddlers often prefer no handles.
4. Easy cleaning. Fewer parts, wide openings and dishwasher-safe components (check the listing) make life easier. Small valves and straws need a little brush.
5. Materials. Look for clearly labelled BPA-free plastics, stainless steel or silicone.
6. Capacity. Smaller cups are lighter for tiny hands; bigger ones suit older toddlers.

Moving away from bottles

NHS advice is to start moving from bottles to cups from around 6 months, and to encourage your baby to stop using bottles by around 12 months. If your toddler is attached to a bedtime bottle, a gradual approach often works: swap one bottle feed at a time for a cup, starting with the daytime feeds. Your health visitor is a good source of tailored advice.

Keeping cups clean

Straws and valves can trap milk and moisture, so take cups apart after each use. Wash with hot soapy water and a small bottle or straw brush, and let all parts air-dry fully before reassembling. Check regularly for cracks, splits or bite marks in spouts and straws, and replace parts that look worn.

Avoid these common mistakes

• Using juice to “encourage” cup use. Water and milk are the best drinks for toddlers’ teeth.
• Letting a toddler carry a cup all day. Constant sipping of anything other than water is harder on teeth.
• Expecting no mess. Spills are part of learning. A bib and a wipeable floor help.
