keeping baby upright after every feed

keeping baby upright is honestly i tiresome task, since it takes much of our sweet sweet sleep time. so whats your to go way to keep your baby upright after every feed? do you hold them yourselves or prop them against something? personally my to go way is putting my nursing pillow of my legs then propping my 2 month old's back a shoulders against the pillow then rocking her so she falls asleep in the little time im keeping her upright, so i can transfer her immediately to her crib. sometimes i worry that my way may not be good for her bones or something idk im constantly afraid im doing something wrong. anyway, how do you do it mostly?
