I have 4. Less then 5 years between the first and fourth. From 2 to >2 was the biggest hurdle and the reason is simple: you have 2 hands with which you can totally control 2 kids.

Edit: and we speak 2 native languages, our kids have grownup in 2 different countries. Sofar they pick up languages pretty easy and I attribute that mainly to not being afraid to learn & make mistakes.
