Hi! Signed up just to reply, Our 2.5 old daughter is bi-lingual (Finnish, Russian) as well and I see your situation.
We both go to work and she's with the nanny (who speaks Russian) 8-10 hours a day, so of course she knows more Russian at the moment. But I don't think it's a negative thing, it takes time to learn two languages instead of one. She switches languages easily, we all laugh when she sometimes speaks her mixed-language.
I'd say go for it, keep on talking English to your daughter and let her learn it, even if it takes time. Most definitely let your wife to talk Portugese since it's her native language (even if she'd speak English fluently.. first language is always first language). Maybe you could take up some lessons as well to catch up their conversation?
Your daugher will soon speak both languages fluently and it will be a great benefit in her life!View Thread
