Flying and Formula Feeding

Flying and Formula Feeding

It is undoubted that breastfeeding is easier when traveling. All you need is your boob and maybe a cover and you are good to go. But for all the formula feeding or expressing mums out there, airports and flying offer a different set of challenges. On the blog we aim to take the stress out of travelling with a formula fed baby so here is my essential guide for flying with a formula fed baby

The rules and regulations of flying and Formula Feeding 

First the good news – the 100ml carry-on limit for liquids doesn’t apply to formula milk or sterilised water. This means that you can bring on enough liquid for baby to last the entire flight. Unfortunately that doesn’t mean unlimited supplies but enough to keep you going and a bit extra.

Traveling with a formula fed baby Through Airport Security

As with all liquids, remember to pack your milk in see through bags and remove them from the nappy bag.

If you are flying with remeasured formula and water I would recommend not using a vacuum flask as it may cause issues when you pass through security.

The only thing that might concern mums going through security is that they might be asked to open liquids to taste going through security. If this concerns you, you could consider buying the newborn ready feed kit. The formula milk in these are 70ml so you don’t need to open them as you pass through security. Warning however this is the most expensive option. Otherwise, you can order formula to be collected at some airports once you have passed through security Be sure to check with your airport if this is an option and also the timeframes for doing so. Many airports need a minimum of 5 days warning to do this!

Some airports will only ask you to open some of the milk. Other airports now have a machine which you can run formula food without opening which means it will stay sterile for the whole journey. 

As always, regulations can change. I recommend using the U.K. Government website to check guidelines before traveling.

Flying with infant formula! What type of formula should you fly with

Are you wondering about flying with infant formula? Worried about which one to take? In truth you have several options. You could take remeasured formula and water. If you this be sure not to use a vacuum flask to store it in as this may cause you issues at security

Personally we use ready made formula. Undoubtedly the more expensive option but it does offer ease. All you need to think about is putting the milk in a sterilized bottle. We actually use chilli peeps teats when traveling instead of bottles. These teats can fit onto all bottled ready feeds. You can simply screw on the teat to the bottle of ready made formula and you are good to go. This saves a massive amount of space in your nappy bag and we all know space is a premium when travelling with a formula fed baby.

Another option is to buy the formula airside. Check which airport you are flying from to see if this is an option. Some of the airports allow you to preorder so check if this option is open to you.

How much formula should I fly with?

If you are worried about how much to pack remember to pack enough to allow for delays and remember that the dry air on the plane may make them thirstier than usual.

When Should I formula feed my baby while flying?

I would advise sticking to your normal feeding routine when traveling but if you can time it so you can get your baby to feed during take off and landing this will help with ear popping and will reduce discomfort for baby! Some recommend waiting until the plane has actually taken off so the baby gets the benefit of feeding one the cabin pressure has actually changed. If your baby refuses to feed at this timothy and use a pacifier instead as the sucking motion does help them pop their ears!

How to sterilize bottles when traveling by plane

When traveling with my little I always try and carry enough bottles to last the entire journey so I don’t have to worry about sterilizing while traveling. If you are limited on space we like to use bottles with attachable teats such as the Chili Peeps Teats which fit most bottles and save on space

    I never even considered how difficult this would be as I never flew with a baby. I am glad that the liquid limitation does not apply. This is a really helpful post to those that need this information.
