Hi people!

My daughter (5 years old) and I are travelling into Europe. We have double citizenship (brazilian and italian) and entered EU using our italian passports.
Next wednesday we are going home in Brazil and her italian passport is valid until may 2nd. Our brazilian passport is valid (her has validity until 2021) and with us. So now I’m afraid and have some doubts:
- Is it ok to show the brazilian passport at checkin and the italian on passport control?
- Is it ok to leave EU only with brazilian passport?
- should I present the italian passport at control and say she has double citizenship?
Since the EU website says I need only a valid passport to leave EU, I think the first option should be ok. Please help me.
