My DH is Dutch and I am American.
Our son is due in April, but our plan is for DH to only speak Dutch to the baby, I understand Dutch and know also plan on talking to the baby in Dutch even though I have an accent and my grammer is not perfect. I will also talk English. I am more than confident that the baby will learn perfect English, so we want to focus our efforts on Dutch.
Our goal for our baby is to speak and read dutch. I don't really care if he has an accent, I just want him to be able to communicate with his Dutch family.
We do go to holland twice a year and my in-laws visit once a year. In addition, we skype every sunday.
I have several children's books, and I am in the process of getting some CD's with children's songs on them that we can sing together.
I know it will be difficult at first, but but once we get used to talking Dutch to the baby, I am sure it will become more natural. Just think of it as the baby does not "understand" English so I just speak Dutch to him.
good luck!
