How far is too far of an age gap?


I know this sounds crazy but my son is 2 right now and I don’t want kids for another 3-5 years (I’ll be 30-32). Is that too far of an age gap? My sister and I were 2 years apart and I didn’t like her growing up so it was hard😂. What do you think? And what’s the age gap between your kids? Thanks!
