Need Suggestions: Still feel older and "different" than other families

Well, I am a definate late bloomer... I was 40 when my bio son was born. Now, at 52 I have a 12 yr old son, 11 yr old daughter, 8 year old son, and am in the process of adopting a four year old. So far I have enver been referred to as grandma, but I am a pretty young looking fifty-ish. I have a lot of "mom" friends, ranging in age from 26 to a good friend the same age as me with a son the same age as my oldest. I really do not worry about my age. And we don't worry about adoption either. Maybe it is because our kids were older when adopted (6 and 9 for the first two adoptions), or maybe it is because only one of the four is biological, but adoption is just a part of life for us. My kids tell people they are adopted (or in the case of the little one, that she is being adopted) as just another fact about them.... I'm eight years old. I'm in the second grade. I'm adopted. I like to ride my bike.
