Find some answers to the most frequently asked questions about your Advanced Comfort Baby Bottle.

Is it ok to put bottles in the dishwasher?

Of course! Pop them on the top shelf though. As with all white and clear plastic things they can get a bit stained and yucky-looking in the dishwasher (blame that bolognese sauce or carrot soup you had last night). If they do get discoloured there’s nothing to worry about - they’re perfectly safe, they just don’t look as inviting!

Why is the teat collapsing when my baby is feeding?

The Closer to Nature Advanced Comfort bottle's round dome valve, which fits onto the bottom of the venting tube is very sensitive as it is made of specially designed silicone material. This can sometimes stick together when not used for periods of time or before first use. To ensure the slit in the dome valve is open you should wash all parts in warm soapy water, rinse in clean water and sterilise.

Re-asssemble your bottle as per the instructions. When assembling your bottle it is important that you check the valve at the base of the stem by holding it to the light to check that the slit in the silicone has not sealed closed. If it has sealed closed, pull apart gently between your fingers to re-open. If the valve has sealed closed your bottle will not vent properly.

I hear bad things about BPA - is it in your bottles? (& what is it anyway?)

All Tommee Tippee bottles are BPA-free. They are made of a plastic called polypropylene that’s lightweight, easy to clean, and completely safe. BPA - that’s (CH₃)₂C(C₆H₄OH)₂ for you science geeks - is a chemical that’s been used in some plastics since the 1960s and it can mess around with your hormones. It’s generally not good, so we don’t use it.

Can I buy bottles with faster flow teats?

Sorry, nope. Most parents stock up on bottles before baby arrives, so all our bottles come with slow flow teats as standard. They’re best for newborns. As your baby grows and can feed more quickly, you can buy replacement teats. We do a medium flow which most babies are ready for at around 3 months, and a fast flow teat which is best from around 6 months. These ages are only guides though - you know your baby better than anyone and will be able to tell when they’re ready for a faster flow.

The valve at the end of the tube has no slit in it?

When assembling your bottle it is important that you check the valve by holding it to the light to check that the slit in the silicone has not sealed closed. If it has sealed closed, pull apart gently between your fingers to re-open.

Can I get spare parts for my bottles?

Absolutely! Chat to a member of our Careline team on 0800 726436, or drop us a message from our contact page.

Can I recycle my bottles when I’m done?

Yep. Our Closer to Nature® bottles are made from polypropylene (PP) that can happily be recycled.

Can I store breast milk in bottles?

Our bottles would love to look after your breast milk. We even have special lids you can pop on to store your milk in the fridge or freezer. If you’re expressing and storing breast milk, our new Express and Go™ range may be handy too - it features a clever pouch that you use to express, store, warm and feed. This means there’s no need to transfer milk at any stage, so you’ll never lose a precious drop!

Why do my Advanced Comfort Bottles leak?

There are a couple of reasons this could happen. The first is simple. Take a look at the domed valve and you’ll see a small slit running across it. This allows air to flow up the straw and out of a small air hole. If water is too hot when you put it in the bottle, it can enter the straw and travel up to the air hole on the screw ring, causing a leak. The solution is to let the water cool for a while after it’s boiled, before you pour it in. According to WHO (World Health Organisation) 30 minutes is the perfect cooling time.

The second reason your bottle could leak around the screw ring is that the round silicone valve at the base of the straw is torn. If that’s the case, please contact our Careline through our contact page. They will provide a replacement if your product is damaged.

Why is my bottle misshapen?

Our bottles have a unique ‘waisted’ design that makes them cute and easy to hold. If your bottle has lost its shape, it could be that you’ve poured boiling water in then put the lid and teat on a bit too soon. Doing this can cause a vacuum to build up, which can suck the bottle inwards into a bit of an odd shape. The best bet (as endorsed by WHO - World Health Organisation) is to let freshly boiled water cool for around 30 minutes before making up a feed. This will make sure your Tommee Tippee bottle keeps its cute waisted shape.
