This is almost OK. Wait until you have twin boys, like me. They are 20 months now, grown at home, no day care ( KiTa as in Germany ;Kindergarden is later on).

They don't speak, but very few words with a meaning ( mama, papa, apa ). But! Here it comes: they speak between them and communicate using a almost invented language. The language is so strange, because is based on using the same word ( twin 1 uses 'bahdi', twin 2 'budji' - approx phonetic rendering), repeatedly but changing tonality, like in cantonese. It's really amazing to see how they can talk each other and coordinate while playing for hours using this language, me and my wife feel we are completly left out :).
