I am hoping for feedback from those with experience with large age gaps. Negative and unproductive feedback, please don't respond.

We have five children already (16, 13, 12, 11, and 10). All five are from our first marriages, although my husband adopted my three. We decided that we wanted to have a biological one together.

Now that we are pregnant, I have questioned what it will be like for this one to be so much younger alone. Other parents I have talked to that had children later have regretted leaving one alone.

All of our other children are so close and have loved having the siblings. They voted that we should have another. I'm not feeling like I really want to go through another pregnancy, but love my children and know I would never regret having another one.

Question being: For those that know someone with a large age gap, or have made this decision, what impacted your decision and how did it turn out?

UPDATE: I guess I'm more concerned about what it's like to be the youngest when all of the other kids are grown and there isn't anyone left but parents to play with. I have one daughter, that through special circumstances, had to spend time playing with just my husband and I and she said she hated it. She missed her siblings. We're just trying to decide if we should have one more after this one as a companion.
