We live in the UK. DH is Spanish. I speak English with th DC (3.10 and 15 months) and he speaks Spanish. DH and I speak mainly English.
DD went through a stage where she definitely decided English was the language to speak. She understands both but really only wants to speak English.
We want DCs to be bilingual. Do we need to make Spanish the language of the house in order for this to happen? DH and I try to, but we always lapse to English out of habit (we knew each other a long time before DCs) .
My Spanish is ok but not fluent. I would make mistakes and be limited in what I wanted to say.
