We brought our daughter home on January 10, and she turned 2 on January 24, so she is defintely a toddler!
We initially thought we would get the referral of an infant, but when we rec'd her referral we just could not pass it up. Yes, there have been some days that are harder than others, but I would not trade having a toddler for anything. As for the language issue...there has been NO issue. We are going to keep her bilingual, but she has had no issues with English at all. She is learning it very quickly and understands everything we say to her.
There have been no attachment issues, either. I was only home 3 weeks with her and DH had 1 day off after we got back from GC, and she knows we are Mama and Daddy and prefers our company, love and nurturing over anyone else. And that is all we could ask for.
So, don't be afraid to adopt a toddler. We had all the usual fears, and there has been nothing that we could not handle. If we could do it over again, we wouldn't want it any other way.
Also, the suggestion to read "Toddler Adoption: The Weaver's Craft" was a good one but keep an open mind. We read it and found it to be "worst possible scenario" stuff, and have had no experiences with any of the tough stuff. I also read "What Size Shoes Does She Wear, A Guide to Toddler Adoption" and found it to be very good and much more positive as far as worst case scenarios.
Good luck with your decision and you can PM me if you need more information...
