Car Seats (Group 0+/1/2/3)

1 year baby car seat. time to change to the next group yet?

Doesn’t time just fly when you’re having fun with your baby? You may have reached the stage by now when you need to upgrade your newborn car seat to the next size up i.e. a 1 year baby car seat. This is not necessarily required in all cases but typically if you had a Group 0 seat and your baby has reached ~10kg in weight. See details on car seat stages here.

Many parents are happy to purchase combination seats from the beginning, i.e. Group 0/0+ meaning that you do not need to change your seat just yet and you have another few months to wait before your baby reaches ~13kg. Additionally, if you bought an i-Size seat this should last you to approximately 15 months.

1 year baby car seatTHINGS TO BEAR IN MIND

If the time has come and you need a 1 year baby car seat, think about the following first to ensure you are well aligned to get the best seat:

  • If you have existing car seat bases and you wish to carry on using them, check that any new car seat is compatible.
  • If your Group 0 seat is part of a travel system, check that any new car seat is compatible. You will probably only be able to find a Group 0+ seat that may be compatible with your travel system as seats from Group 1 or higher are meant to remain in your car. So if you buy a Group 0+ just so that it is compatible with your travel system, you will only be able to use it for a few months. It’s probably not worth it and it may make sense to consider Group 1 and above. You will therefore need to use your travel system’s normal chair as your baby should be able to support his or her head by now. This unfortunately means that you will need to move your baby from seat to seat. If however you are starting out and are looking for a travel system, consider a Group 0+ newborn seat.
1 year baby car seat. do i DEFINITELY NEED TO BUY NEW?

Most parents prefer to buy a brand new car seat and that is the general advice given in most cases. If you do buy new, you will know that it has never been in an accident. This is of course the best option for you if you can afford it but there are suppliers who refurbish seats and provide a guarantee for them after testing. This could be a viable option for you.

WHAT TO LOOK FOR in 1 year baby car seats.
  • Rear facing for as long as possible is always recommended. i-Size products will allow you to extend this the most (up to 4 years in some cases) and they will be secured to your car with ISOFIX brackets making them very safe.
  • Group seats are great value for money and worth considering. Common groupings at about 1 year are 0+/1, 0+/1/2 and 1/2/3. There may appear to be some overlap in the weight of these groups when you search but don’t let that worry you. The actual product’s specification should override any other information you receive.
  • Consider a Group 1/2/3 seat if you intend on buying a combination seat where Group 1 starts when you want it to. i.e. at 9 or 10kg which is typical for a 1 year old.
  • Adjustable headrest and harness to ensure your baby is always comfortable as he or she grows.
  • Reclining seats without having to remove them to reset the incline position make life a lot easier.
  • Any seat should have its own Harness.
  • Enough cushioning or head restraints and side impact protection.
  • Removable and washable materials.

NOTE: When reaching group 2 (~15kg) your child will typically start to use your car’s 3 point adult seat belt with the car seat rather than the harness provided by the car seat.

  1. I don’t have a baby but this is great information for people who do. What are the risks involved with a used car seat besides it being in an accident if any? And what are the price groups for each type of car seat?

    1. Hi Liberty. Thank you for your comments. The other main risk with buying second hand car seats is wear and tear on any mechanical parts. For example, if it was an ISOFIX seat that was removed from a car very often, there may be some play when secured to your car. This could potentially increase the risk of it coming loose or giving your child whiplash with any jerky movements, hard braking or an accident. Regarding the price groups for each type of car seat, due to the large variety of seats, it’s difficult to answer. In general though, £100 should cover any mid range seat of any group on it’s own or as a combination seat. Hope this helps. Let me know if you need any more info and thanks again for dropping by.

  2. I really appreciate the research you have done on baby car seats.

    Your information helps me make a decision on which type of baby car seat I need to get for my grandchild’s visit this summer.

    Your website is inviting and informative.

    I am glad I came to visit.

    1. Thank you very much for your kind comments. I’m glad you found the site informative and let me know if I can help with anything. Good luck finding the right seat and have a great summer with your grandchild.
