Hello double nationality couples!

I have a question for you all who have/are having a baby and each of you is from a different country. When the baby is born in which language are you going to talk to him/her? In your mother tongue, English (If you live in an English speaking country) or in your husband's/partner's/bf's native language?
I've always wanted to talk to my baby in Spanish as I'm from Spain even though I live in the UK and my husband is from Pakistan 🙈
