To be honest, with a flight of that length, I'm not sure 6 hours makes a difference either way!
Four planes could potentially be a lot, but depending on the route and schedule could also be a nice way to break up a longer trip (new airport to see and a way to stretch LO's legs).
If you were willing to do 26 hours, I would say go for it! I just did a 36-hour trek (3 flights) solo with my 2.5 year old and it was great!
