Digestion question

How long do you hold you little ones up after eating? My daughter is 4 months old and eats about 120ml every 2 hours. So I was just wondering how long everyone else let’s there children digest. When she was a newborn I know it was 30min of holding up after burping but now I’m not sure if it’s the same or is it different since there bigger and used to eating from a bottle.
