I have this crazy notion that I do n't have enough time . What this does is cause me to plan and re - plan so that I fit all of my interests and goals into my life . We talked about having another child and I confessed that my greatest fear was that we would n't be able to .

Question: What may be the reason why they do n't think they can have another child ?
Answer: They do n't want to let their only child down .They always think about the negative side of things .They 're too old .They 're letting their anxiety rule their life .
