7 years old infant?
i’ll take it as 7 month old, from my experience, its best bring baby you try out the carseat to see which baby like to seat it, during this MCO the shop Mylovelybaby is open if you want to try, they got outlet in setapak/puchong.

i bought chicco nextfit zip max for my baby,
it is a little bit expensive but totally worth it, i try not to skimp on safety.
