So, how does the Grow with you compare to the Frontier? 

The new Britax Grow with you Clicktight is basically the same as the Britax Frontier. The main difference between the two seats other than the Frontier had a black plastic shell, while the new Grow with you Clicktight has a grey shell is the harnesses. 

The Grow With You Clicktigh has a lower weight limit (65 pounds or 29.54Kgs) while the Frontier had a 90 Pounds or 40.9Kgs harness limit. Which coming to the think of it is not much of a big deal, as average 5 year old boy or girl (75th percentile) is around the 20Kgs*. The Grow With You Clicktight will allow for an average 6-7 year old (or a large 5 year old) to stay harnessed. 

Once a child exceeds the 29Kg limit for a harness, the seat transforms to a Seat belt booster for a school age child who will be mature enough to use the car seat belt in that booster mode with a seat belt.

The Grow with you Clicktight is a replacement product for the Britax Frontier. 

The Britax Grow with you Clicktight has a 1 year manufacturer warranty and a 9 year life span from the date of purchase.

Both use the same wide, breast-shaped teat design — the difference is in how they handle air reduction. Closer to Nature has a built-in anti-colic valve in the teat that reduces air ingestion during feeds. Advanced Anti-Colic goes further, with a heat-sensing tube at the bottom of the bottle that actively vents air out of the milk before it reaches your baby. For most babies, Closer to Nature is plenty. For babies with more significant colic, wind, or reflux, Advanced Anti-Colic is the better choice.

Yes — the Closer to Nature range is one of the most recommended bottles for combination feeding. The wide, breast-shaped teat encourages the same broad latch breastfed babies use at the breast, reducing the risk of nipple confusion. Always start with a slow flow teat for a breastfed baby regardless of age, and introduce the bottle around three to four weeks once breastfeeding is well established.

For many parents, yes. The Natural Start glass bottle is made from premium borosilicate glass — odour-free, heat resistant, and very easy to sterilise. It's particularly practical in the newborn period when you're sterilising frequently and mostly feeding at home. The main trade-offs are weight and the risk of breakage. Many parents use glass at home and plastic when out and about.

Start with slow flow for all newborns — whether breastfed or formula fed. Move up to variable flow when your baby shows signs of frustration, takes too long to finish feeds, or falls asleep before finishing. Fast flow suits confident, efficient feeders from around six months. Always let your baby's cues guide the decision rather than age alone.

Yes — both ranges include anti-colic features. Closer to Nature has a built-in anti-colic valve that reduces air ingestion. Advanced Anti-Colic takes this further with an active venting system that removes air bubbles from the milk during the feed. For babies with significant colic, the Advanced Anti-Colic bottle is the stronger solution. For a more powerful anti-colic system, Dr Brown's bottles use a fully internal vent system that is clinically proven to reduce colic.

The Perfect Prep Machine makes a fresh, perfectly mixed, body-temperature formula bottle in under two minutes — safely. It delivers a shot of hot water (over 70°C) to kill bacteria in the formula powder, then tops the bottle up to the correct volume with filtered water at room temperature. The result is a safe, correctly mixed bottle at the ideal feeding temperature, every time. The Day and Night version adds a quiet pump and soft night light for night feeds. It requires replacement filters every three months — available at Babies.co.nz.

As a guide: 2–3 bottles for occasional bottle feeding of a breastfed baby; 4–6 for combination feeding; 6–8 for exclusive formula feeding. The Closer to Nature 260ml 3-pack is the most practical starting point as it gives you enough bottles for a full day without constant washing.

Yes — all Closer to Nature, Advanced Anti-Colic, and Natural Start glass bottles and teats are dishwasher safe on the top rack. Replace teats every two to three months or sooner if you notice any thinning, stickiness, or discolouration.

Both are excellent, widely trusted brands. Tommee Tippee's Closer to Nature teat is slightly softer and more flexible, which some babies find easier to latch onto. Philips AVENT's Natural Response teat uses a unique J-shape that releases milk only when your baby actively drinks — a more precise mimicry of breastfeeding. AVENT also offers more granular teat flow options (six levels vs Tommee Tippee's three). If you're combination feeding and want the most breast-like bottle experience, AVENT Natural Response is worth comparing. If you want a trusted, simple bottle with strong anti-colic performance, Tommee Tippee Closer to Nature is hard to beat. Read our full Philips AVENT buying guide →

The key difference is anti-colic power. Dr Brown's internal vent system is clinically proven to reduce colic and is the stronger solution for babies with significant wind or reflux. Tommee Tippee's anti-colic valve (Closer to Nature) and heat-sensing tube (Advanced Anti-Colic) are effective for most babies but less comprehensive than Dr Brown's approach. On the other hand, Tommee Tippee is simpler to clean — fewer parts, no internal vent tube to wash — and the breast-shaped teat is widely regarded as one of the best for combination feeding.

Most paediatric guidance recommends transitioning from a bottle to a cup around 12 months. Tommee Tippee makes this easy with their integrated cup and sippy range. The transition from bottle to sippy cup is smoother when you stay within the same brand — the familiar Tommee Tippee feel and quality helps babies accept the change more readily.
