Questions and Answers about Dr Brown’s Natural Flow Teats

We have many enquiries here at Dr Brown’s about teats. Ranging from what teat size the bottles come with to what size teat should my baby be on.

In this blog post we have identified some of the questions that we regularly get asked.

So, question number 1,

‘What level teat do I have?’

To find this out you have to look on the rim at the bottom of the teat. It will say Level and then in a circle the number. However if it was a preemie teat it’ll say ‘P’ and Y cut it’ll say ‘Y’. Circled below in where you’d find this information.

Question 2,

‘What size teat should my baby be on?’

The basic answer is every baby is different, some babies require slower or faster teats than other babies. However we do provide a recommendation for the different levels of teats, however these are only provided as guidelines to us to help you make the decision to move your baby on to the next level.

Preemie Teat – for Premature Babies.

Level One – for infants 0-3 months (Flow rate- 57% faster than the Preemie Teat)

Level Two – for infants 3-6 months

Level Three – for infants 6 months plus

Level Four – For infants 9 months plus

Y Cut Teat – Allows thicker feeds which would block the hole of a normal teat.


Question 3,

‘What teat size would I need for my X week old baby who is one a thicker feed?’

This is where it gets trickier. Picking teats when you have a thicker formula is based on trial and error. We would normally recommend trying a level higher.

For example, if you had a three week old baby on a thicker feed we’d suggest going from a level 1 to a level 2.

We would also suggest propping your baby up whilst feeding using a faster flow teat, but its best to check with your Health Care Professional.

Question 4,

‘Why won’t my preemie teat fit onto my 120/240ml bottles?’

The preemie bottle is something called a ‘standard neck bottle’. This basically means that the neck of the bottle is smaller in comparison to our other bottles. This is because when you are feeding a smaller baby you need a smaller bottle.

The preemie teat flow is slower than the level one. The level one is about 57% faster than the preemie.  The level one teat will drip about one drop per second with water in the bottle and the preemie flow takes between 2 – 3 seconds per drop.

Our 120ml and 240ml bottles are ‘wide neck bottles’ and these are sold in the UK along with level 1, 2, 3 ,4 and Y cut teats.

Question 5,

‘How do I clean my Dr Brown’s teats?’

You must never use the vent brushes to clean the teats. If the vent brushes are forced through the tip of the teat, this can either widen or split the teats making them unusable.

It can also cause the teat to split. You can purchase our bottle and teat brush to ensure that the teats are cleaned correctly and effectively at

Travelling with a baby

By 6-month-old Nicholas Edwards with a bit of help from his Mum

What’s this? Mum waking me early for a feed! I’m only 6 months old but even I can tell she could do with a few more hours’ sleep. But no, I’m loaded into the car, along with the luggage. Now I remember – we’re off to see my relatives in some far-away place called the UK.

From my vantage point in a back-pack high up behind Dad I’m fascinated by the people, lights, noise and interesting sights of Brisbane airport. Being high up means I’m not jostled and Dad’s hands are free to juggle passports and tickets. Mum looks like a camel, with a heavily laden backpack full of my stuff for the journey, leaving her hands free to attend to me.

I have my own 10kg luggage allowance, but I only need to pack my favourite clothes as my nice aunty in England has arranged to borrow everything I’ll need from friends. Mum and Dad still seem amazed by how much equipment a little boy like me needs.

I wanted to wear something smart for when I first meet Grandad but Mum insisted on a jumpsuit, so it’s not tight around my pot belly and my feet stay warm.

My expressed breast milk in my Dr Brown’s bottle and baby food make it through security. A gruff man looks at my passport, at me and then back at the passport again. I frown at him intently trying hard to look like my serious ‘no smiles, no laughs allowed’ photo. Even I’m surprised how much I’ve changed in the weeks since it was taken. To think this passport is valid for 5 years!

We’re allowed to board the plane first, where beautiful ladies smile and tell me I’m gorgeous. They even gave me a little toy. I think I could get used to this!

Luckily Mum and Dad pre-booked me a bassinet and checked in early to make sure our request was honoured. The poor little baby in the seat behind us was not so lucky.

I startle at a loud rumbling noise and the world seems to be moving very fast. My ears ache and Mum slips a dummy into my mouth. I prefer the real thing, so wiggle sideways in my seatbelt and am flying happily with mid-air refuelling from Mum!

Out come my favourite toys, as well as some new ones especially for the flight. I’m also allowed to watch TV, which is usually a no-no, but I think Mum is just happy I’m quiet. Yippee!

I’m pretty content most of the flight. The nice stewardesses serve Mum and Dad’s meal separately so I always have someone to hold me. They also kindly warm the purees that Mum brought for my tea.

Singapore airport is even bigger and brighter than Brisbane. Mum lays down my rug so I can have a ‘kick-around’. It’s great to stretch my little legs before the next flight to Manchester.

My work-out does the trick. After fighting sleep for 18 hours, my eyelids finally become too heavy and as I finally drift off in my comfortable bassinet, snuggling my favourite blankie I hear Mummy whisper ‘A small glass of wine please.’


Why is my baby crying?


Do you know that crying is your baby’s only one way of communicating what he wants. Newborns cry between one and three hours a day, but by the time your baby is a few weeks old, you will probably be able to distinguish which cry is a hungry cry, a colicky cry and which one means he needs a comforting cuddle. It’s relieving to know that there are only a handful of things, which actually make newborns cry, so it may be a process of elimination till you work out which it is.

Colic is categorised as persistent & severe crying, occurring mainly late afternoon or evening, lasting at least 3 hours a day and 3 days a week.

78% of Healthcare Professionals agree that the most common cause of colic in young babies is caused by digestive or feeding problems, including swallowing air

Dr Brown’s Natural Flow Baby Bottles, are clinically proven to help reduce wind related colic.

Do remember that if you still feel there is something else bothering your baby, you should consult your health visitor or GP for further advice
