Why Are My Bottles Leaking?

We always hear how so many of you mums absolutely love Haakaa’s baby bottles, whether it’s our Gen. 3 Silicone Bottle that transforms into a 5-in-1 feeding system, or our ergonomic Gen. 3 Glass Baby Bottle with its off-centre nipple. And it’s no wonder why! With gentle medical grade silicone teats that mimic the shape of a mother’s own breast while feeding, our bottles are more readily accepted by babies, making them fantastic for transitioning to bottle feeding or for mixed feeding!

Every now and then, some mamas will have their bottles leak in certain situations. While some brands’ baby bottles can leak because of defects, it is more often the case that the bottles are not being used properly. We’re here to explain some easy solutions to ensure you get the most out of your Haakaa baby bottles, without leaking any of your baby’s precious food!

If your bottle leaks while feeding…

Then it may be because the nipple flow is different to what your child needs. Haakaa bottles come with three different sized nipples to suit the different stages of your baby – Slow Flow, Medium Flow and Variable Flow. If the flow rate is too slow for your little one, they will have to suck harder to get more milk. This can push air up into the anti-colic vent, causing pressure to build and pushing liquid out of the neck of the bottle – causing leaks! To fix this situation, your baby may be ready for the next nipple flow level. As a general rule of thumb, the older the child, the faster the flow rate that is required.

If your bottle leaks while preparing formula or warming milk…

There can be a range of reasons why your bottle might leak when you’re preparing milk for a feeding. One of these reasons might be that the temperature of the milk is too warm. This can increase the air pressure inside the bottle and cause leaks, as the air tries to find its way out.

Over-tightening the pieces of the bottle while assembling it can also cause your bottle to leak, surprisingly enough! To prevent this, ensure that the attachment ring is not tightened too much on the bottle. Twist on until you feel resistance – and when you do, do not twist any further as the ring is screwed on tight enough. If you over-tighten the ring onto the bottle too much, it may lead to damage – which is something you definitely want to avoid!
