Role modeling is the best teaching mechanism. If YOU show a love of yiddishkeit, your children will learn it. If you find it difficult what do you expect.
Furthermore, if you take a look at the school system, only in pre-school do you see that ahavah and fun being displayed. As soon as you hit the regular classes it is all serious again. There is less and less arts and crafts, music, singing, etc. and more, work, work, work. There is less of a mitzvos aseh and more chumras and lo tasseh. In pre-school it is all about what we do. In first grade and up they teach about what we don’t do.
