Yes absolutely and without a doubt yes yes yes.

My husband is an immigrant. He comes fro an English speaking country so we don't have the hurdle of language that you will have with your stepson, our language issues are so minor it's not even funny. However, we do have some cultural differences. Kids take that stuff on so easily. They take language on pretty easily too, to be honest. (my kids after three years, are no longer confused by Britishisms.)

I think it's absolutely wonderful that you want to keep your own heritage alive and functioning within your household, and I think you taking on your stepson as one of your own in this respect is absolutely the best thing you can do. It truly blends the family and as he grows and he learns along with his siblings, he will feel better about himself, you, his mother. He won't feel like an outsider. And I am of the belief that treating your stepchildren different than you would your biological children does you, your spouse, and most importantly the child, a disservice.

Your desire is one born of a good heart. Go with it. Love your wife, and love your children. Make your family what you want it to be.

I just want to hug you. Seriously. Parents like you are amazing human beings.
