Otherwise though, this bottle is quite easy to clean and came out almost spotless when we cleaned it in a dishwasher and washed it by hand in a sink. Accidents have occurred when babies have been left alone with drinking equipment due to the baby falling or if the product has disassembled. Tooth decay in young children can occur even when non sweetened fluids are used. This can occur if a baby is allowed to use this type of beaker for long periods through the day and particularly through the night, when saliva flow is reduced or if it is used as a soother. Our verdict: Easy to use and watertight, this practical water bottle from Ion8 also sailed through our durability tests.

There are also lots of nooks and crannies that dirt or sand can get wedged in, something we found when we rolled this bottle around in a sandpit. This bottle has handy measurement lines on the side, so you or your child can trace the amount of water drunk through the day. Straws: Once a child has grown out of baby bottles the next step might be a bottle with a straw. These can either be made of tough plastic or softer silicone. We've found that some of the softer silicone straws don't stand the test of time and children will nibble through them given half a chance. The product presents a risk of choking. Nuby is voluntarily recalling the Incredible Gulp Cup due to a small number of defects on the spout and straw assembly, which in some instances means that the spout could detach when pulled with force and this could become a choking hazard Corrective action The type of water bottle you need will vary depending on the age of your child, and what life stage they're at. The bottles we've selected for our tests are aimed at preschool and young primary school children.

Hazard: The product poses a risk of choking due to a small number of defects on the spout and straw assembly, which in some instances means that the spout could detach when pulled with force and this could become a choking hazard.

Our verdict: Although children will love the design, we found a number of issues with this Nuby water bottle during testing. It came out of the dishwasher with lots of dirty spots still on it, particularly around the spout and underneath the lid. These spots were also hard to clean when handwashing, and we'd wager they would often be missed. Our verdict: It's a well designed leakproof bottle available in a variety of fun colourful designs. Rolling it around in a sandpit did allow some grains to get under the flip lid, but these were easily brushed off without much fuss. Children’s drinking cup available in dinosaur, unicorn & fox designs, with spout and drinking straw.Note: It is important that the lid is thoroughly rinsed by allowing water to flow across every surface to remove any food residue and ensure hygiene. Shake well to allow any trapped water to escape. It's a tough bottle, too, suffering only light scratches after we dropped it 10times, when full, onto a hard surface. Both of our three-year-old and five-year-old testers were able to fill and tighten up this bottle without it leaking. It also came out completely clean from the dishwasher, and again when we washed it in a sink, with no tough-to-reach spots where dirt and bacteria could be left to linger.
