Bilingual household

I think that a child that grows up in a bilingual home is very lucky. Your daughter will speak fluent Czech and English. You know English to a high standard so it might be possible for you to talk to your daughter and your friends in Czech and English if you are happy to do this. I went to university in Wales and all my lectures were in English. If another lecturer cam into the lecture room he or she spoke in Welsh to the other lecturer. I am a primary school teacher and in my first year of teaching I taught a girl with a English mum and a French dad. I also taught a girl from the Caribbean Island of Martinique. Both girls spoke in fluent French together at play time. Speaking two languages fluently is excellent.

I don't see any problem in talking to your child with your native language. Here in our country, we have lots of different dialect in every island though English is our second language. It's very amazing to hear a child talk in different language, a skill they can be proud of when they grow up.

I suggest that you continue to talk to your daughter in your native language, Czech. Since English is an international language, she will learn it not only from her father but also from her friends. So, just keep on talking to her in Czech even in public.
