For Stroller, personally I would go for up to 3-5 years (depends on lo weight) . If lasted only a year you may have to buy again 😅 baby outgrow very fast.
For first few months, I used baby carrier, for me easier to move around such as public toilet , go out alone to buy stuffs etc I let baby sit stroller when recommended at baby’s weight ( which can last few years after that)
Infant car seat can use prolly up to a year, then gotto change to toddler/kid size . Can get convertible type or which can last U few years .
Depends on your comfort zone too.
