Transitioning from 2-3 kids?

So I have a 2.5 year old and a 6 month old and thinking about possibly adding #3 next year (so falling pregnant sometime this year). The transition from 1-2 was really easy and it has honestly been smooth sailing. The dynamics are really nice and everyone’s happy but deep down I know I would love more babies. Would love to hear experiences on people going from 2-3? My hubby is abit like ‘mm I don’t want to upset the routine and dynamics because of how easy it’s been.’ Am I crazy?
