Just buy a simple yet non-expensive normal carrier. You can get a non-branded one from Shopee and most costs less than $50. Very useful if you were to go out alone with baby. Don't buy the sling type unless for newborn/infant because it's just 1 sided. As your baby grows and becomes heavier, your shoulder will ache and pain from the weight.
if you plan to go somewhere nearby but don't intend to bring stroller out then baby carrier will be useful.
