Depends on your baby. My son used to be on the pram most times and does not like to be in a carrier. While for his baby brother, he can only be in the pram not for too long so most times when we're going out I will babywear him but will also bring along the pram in case I get tired from babywearing him or if he sleeps.
it comes in handy when baby is bigger/heavier and it is a hassle to use a stroller
