Extend2Fit

If you're really set on a convertible I would just make sure they will fit for a newborn! I have [this one](https://www.gracobaby.com/shop/car-seats/toddler-car-seats/convertible-car-seats/extend2fit-convertible-car-seat/SAP_2216092.html) a Graco Extend 2 Fit and we've used it since he was brand new!

We've only used the convertible seat! We have a Graco Extend 2 Fit all in one. The only car seat he will ever need! No regrets. When he was small I held him, carried him, used a stroller, or wore him when we went out and about. Once he could sit up around 5 months it was a bit easier because then he could sit up in the shopping cart but other than that it was great

more expensive does nooot mean safer! you can search “(car seat name) safety rating” & find results i personally like a convertible seat & just using bassinet on a stroller or wearing baby in a wrap/carrier because infant seats only last until around age 1. convertible car seats last until they’re in a booster (8yo ish depending on weight & height) here’s a bunch you can look into because there are tons of options out there my favorite infant seats in cheapest to most expensive order all in usd joie rue $169.99 graco snugride snugfit dlx $239.99 graco gomax $249.99 joie mint latch $299.99 top favorite - chicco keyfit max zip cleartex $299.99 uppababy mess v3 $349.99 britax cypress w/ alpine base $379.99 nuna pipa aire rx + relx base $650 for convertible seats i personally don’t like any rotating seat because they all have low rearfacing limits & extended rearfacing is absolutely the safest thing you can do. one of the only things you can control as a parent safety wise. most of these also can be used for a newborn 50lb rearfacing limit ⬇️ graco extend 2 fit 3 in 1 $269.99 graco 4ever extend2fit $379.99 britax one4life $439.99 britax poplar s $399.99 nuna rava next $580 under 50lb rearfacing limit ⬇️ joie saffron si 4 in 1 $249.99 graco 4ever dlx $319.99 chicco one fit max $379.99

Seconding extend to fit. My kids are all 90s percentile plus in height and have easily rear faced past age 4 in this one! 

We loved our Britax Boulevard but it was not at all good for bigger kids rear facing longer! I think the weight limit was 35 on latch install which some of my kids hit before age 2. We had to change to Diono Radian and Graco Extend to fit to keep them rear facing.

In that case, a little more info - Joie and Graco are owned by the same parent company. The Graco Slimfit R129 and Joie Everystage R129 are the same seat under the covers. Exact same Which/ADAC rating. The Graco is normally cheaper but the Joie sometimes tips it if it's on offer and the Graco is not. The ADAC rating was good, which is reassuring because the result is averaged between the rear facing and high back booster mode meaning it likely has good performance in both modes. It actually performed better than the result of the best forward facing harness + high back booster combo seats which are fitted with isofix. Likewise Joie Steadi and Graco Extend are very similar to each other (not sure if exactly identical). People tend to find their child is too tall for the seat before they reach 105cm, even though that's the limit on it. Halfords tend to stock all of these if you wanted to compare somewhere you can try them in the car. With the 105cm/21kg weight limit of the Slimfit/Everystage, he'll probably hit that around 3 if he stays on the same centiles, so you'll likely need to swap to an extended harness seat later on. Beware that a lot of seats advertised as extended harness have a 105cm limit on the harness. You will need a 125cm limit at that point, but the FF ones are cheaper than RF and probably still will be in a couple of years' time. There are a few of these on the market now. OTOH a lot of children drop centiles as they start moving so you may well find his growth slows down. It will naturally slow down soon anyway but I mean even when they have rocketed through centiles in the first year - my 98th centile 1yo ended up bang on 50th centile by 4 years old.

We have an E2F in a corolla and my 6’3 husband can still fit in the passenger seat. Its a little tight for him but still very doable.
