Our DS is 3, and I really want another one, DH doesn't want another one ( reasons: cost, all the hard work, age - he is 43). I feel really guilty about DS being an only child. Feel jealous when my friends are haivng thier 2nd babies. I keep thinking about getting pregnant 'by mistake'. Age is an issue too - I'm 38. Just feel so upset about this. Is there any one else feeling like this?
