I don't think people should have another child JUST to give their first child a sibling and NO i don't think it's the greatest gift you could give them.. your LOVE, TIME and AFFECTION is the greatest gift for a child followed by SUPPORT & UNDERSTANDING.

Personally i love that my girls are close, they seem to share a bond that no-one else could share with them but in saying that in 20yrs time they could hate each other.

Please don't let your friends words annoy you, do what is right for YOUR family and what your heart tells you to do, some people have no idea what affect their words have on others... either way i'm sure your an amazing mum who has her DD's best interests at heart.
