Hi, I am a full-blooded Czech living in the US. My husband is American and we have a 7-month old daughter. I talk to her in Czech when my husband is not present (at work) so I hope that way she will learn both languages with no problem. My friend who is in the same situation says that her daughter (who is 3 now) understands but refuses to speak in Czech. I also heard that it is better for the foreign parent start speaking in the other language when the child is about 2 so he/she doesn't get confused...Anyone has any experience with this kind of stuff?? Thanks!
