my eldest 2 are 18 months apart, when they were little it was great, it got harder as they got older, shopping was hard, imagine shopping with your 4 year old and his best friend and you get the picture. Since they have grown a bit they are competative and argue lots but are still best mates underneath it all, just very different people.

The difference between my youngest 2 is just short of 3 years and i'd say thats much harder.
