Get a bassinet for the 4-6 months as baby will likely be sleeping next to your bed. Any crib would be fine tbh, I wouldn't recommend a mini crib (we thought babies are small, want do they need that space for). We end moving our kid to a floor bed at 10 months. We did a newborn seat (rear facing) then upgrade to a convertible at 10 months (big baby). Having a newborn seat that is compatible with your stroller is really handy. The stroller was the most important part, my kid is 3 and we still haul it out for trips with lots of walking. We are also in a very walkable area, so your milliage may vary. We got the Uppababy Cruz +Mesa car seat. If you are close to a retail store, definitely go try out a few brands. I'd suggest a convertible seat that is easy to disassemble and wash. We got the Diono Radian 3RXT and it's work to clean.

I have 3 car seats in the Y (I had 3 under 3.5 a few years back). I swapped one of the car seats for a booster and it's a bit difficult for my oldest to buckle (got him seat belt extenders so it does help). It has a lot of storage space so I can see it being good on road trips. Is it safe? It works for me, but your few month old will probable require a more robust car seat / carrier (now my kids are older) that may make it impossible to do 3 across. I bought 3x of the Diono 3xt or xr, forgot which one. Never heard a complaint about comfort. They love Netflix so theres that ha

I have a couple of these and ended up getting Diono slim fit (3rxt or similar). I believe they can be used for infant too but I have only use mine forward facing.

Currently have 3 slim (Diono) car seats in the back of our Outback and the back our a smaller Crosstrek. I thought we needed a new car but new car seats was a much better solution for us.

I used the litemax with my first and she was content in it. Later we got the Graco 4ever and she was okay with it but we got a third car seat the diono slim and she loves this one.

Wife has all graycos in her SUV. I liked the diono better so went with that for my truck. Now she likes those better and also wants them for her car… sure let’s spend another $600 on car seats

Currently have a Silverado 2500 and there’s some room still, but the gladiator cab is obviously a bit smaller

I three Diono R3s. That’s about as slim as they come. Currently have a Silverado 2500 which has plenty of room. But if I downsized it would be between a Gladiator and maybe a Colorado.
