On the other hand, children learn their "first" language not as much from parents, but mostly from their peers. So, whatever you speak at home, doesn't really matter.
We had a very similar experience - teaching your kids a different language in a vacuum (i.e. it's pretty much just you) is very difficult. It's much easier if they, for example, also attend your native language school, preschool or lessons. Nevertheless, even some base of any language at childhood will help if you for example move to another country for work and your kids have to quickly pickup yet another language quickly.
