Is there a way to adjust the bottom buckle? It seems to sit too low on my 3 month old, bringing the straps across the thighs rather then resting over the pelvis.

At what weight/height would you recommend removing the extra padding in a Millenia? My 6 month old looks a bit squashed in rear facing mode but I can’t find any advice on the safest time to remove it.
1 answer
Hi Joanne G, thanks for your question. We would recommend that the padded insert may be used for smaller babies in rearward facing mode. Discontinue the use of the padded insert if there is insufficient room for the child or shoulders have reached the lower shoulder height marker. Kind regards, the Britax Safe-n-Sound team.

I have bought my Britax safe n sound millenia (purchased 2017) on holiday to Koh Samui in Thailand. I would prefer to have my daughter in the rearward facing position as she is at home in Australia, but the hire car doesn't seem to have an anchorage point. Is it possible to use it rear-facing without the top tether or does it have to be forward facing?

Hi Claire DC. thank you for you're question. The Safe-n-Sound Millenia Can only be used as per the manufacturers instructions and the upper tether strap is required for use. If you have any further questions please contact us on 1300 303 330. Kind regards, the Safe-n-Sound team.

Hello we have a Mitsubishi ASX 2017 and the buckle seems to be very short which locks in behind the seat as we have to lift and angle our baby up to place him in and out of the car seat. It’s a mission for us as parents and even more uncomfortable for our baby. What do you recommend? Why would it be an added issue? Hopefully we shouldn’t have to spend more money on a seat we purchase hoping it would provide our baby with safety and comfort you would expect from such a product.

Hi Eves, thanks for your question. It sounds like you may need to addition of an extension strap to make the top tether long. These are available from your place or purchase or on our website - https://www.britax.com.au/accessories/300mm-extension-straps/ or https://www.britax.com.au/accessories/600mm-extension-straps/ these are available in 300mm or 600mm.

My 2 year old is forward-facing in the Britax Millenia, but I find his head falls forwards when he falls asleep. Can the seat be reclined for a more comfortable seating position, or does it need to be used fully upright when forward facing?

Hi Britax, I have converted to forward facing for our 10 month old because he’s just reached the marker with the infant padding insert in, but the instructions say to take the insert out when you change it and this puts him just under the marker.. should I reinsert the padding? Thanks.

I have a safe and sound millenia installed in a triton 4wd by seat belt (using an extension strap) but I have noticed the top tether strap (not the outside strap that I loosen and tighten to put the baby in and out of the seat but the strap on the other side) has loosened slightly, how do I retighten this strap?

When in the forward facing position with isofix I can’t seem to recline unless I loosen the isofix. Is that right? It’s a pain if baby falls asleep while driving because my passenger can’t lean back and recline it without loosening the isofix straps

Can you use the fully recline position for forward facing? The base of the seat seems far away from the back of the car seat.

The Millenia SICT has a few recline position however we aren't clear what you mean by fully recline position as this seat has rear facing recline position then forward facing upright recline position.

Has anyone taken this car seat to the UK? And used it on a plane?
1 answer
Hi Sally, thanks for your question. The Millenia SICT is aircraft compatible however we would recommend that you check with your airline before flying. Many countries have laws for using child restraints and their standards differ from Australia. Laws vary from country to country and even state to state. Countries with strong laws are European countries, USA, Canada, Japan and South Africa. Many vehicles around the world are not yet fitted with a child restraint upper anchorage point or fitting thus to use an Australian seat an upper anchorage fitting needs to be installed. There will be no fittings in Taxis and most rental cars. In many developing countries there are no seat belts in which case a child restraint is of no use at all. Your child seat may be used in some countries like Europe, USA and Canada but you need to check with your rental car company or if you are buying a car check with your insurance company and local police. Many rental car companies do hire locally compliant child restraints in most of the above countries. Please feel free to give us a call on 1300 303 330 if you would like to discuss this with us in further detail. Kind regards, the Britax team.

My 6 mth old baby has just moved from the maxi cosi AP capsule to the Britex Millenia in the rearward facing position but I find the incline is very steep and bubs head falls forward when sleeping. Can the incline be adjusted for a 6 month old baby? I am assumming the incline would be far less steep for a baby 0-6 mths?

Hi. My daughter is two weeks off being one, she is still rear facing and under the line that says must be rear facing under this line. I’ve read places and hear from people that after 6 months they can be forward facing, is this true? Can I turn her around now? Thank you.

HI Libb, thanks for your question. If your little one is still under the rear-facing marker so must remain rear facing until she reaches that line as per the instruction manual.

My daughter is 13 months and nearly at the line at which I am meant to turn her forward facing. I find this a bit odd as yes she is tall for her age 77cm but the deaf is meant to be rear facing for 2-3 years and 77cm is a very short 2 year old. Am I meant to be taking out the padded insert so she stays rear facing for longer? Or is there anywhere I can confirm the height in cm in which they must be turned forward facing? Thanks
2 answers
yes definitely too short to be forward facing that early, my 12mth old son was 80cm and still able to rear-face with this carseat. all car seats will have an approx rear-facing age limit, but this is only a guide as other factors such as height, medical conditions etc come in to play. definitely take the padding out, that is the first step before forward facing. you will find without the padding she will go way back under the markers. the millennia as far as I'm aware has the deepest seat of all car seats so she should get a lot of time refacing before having to switch. hope this info helps.Hi Gull, thanks for your question. We would recommend that you removed the insert as this will give you little more room in rear-facing mode.

How are these with having a Maxi Guard pro and Millenia rearfacing in the back of a Mazda 6 Room wise?
