Hi J.,
We're a family of 3 and love it. We also started much later than you (I was 37 when I had our daughter; she's now 6) so that was also a factor. I'd recommend writing out the pros/cons of having another child. From our perspective, this is what we enjoy about only having one child (I might add that we DO live near family and our child has cousins close in age that she is close to)
1. One child is less stressful! My patience is rarely stretched too thin (I'm NOT a very patient person by nature)
2. More funds on hand for outings/vacations -- we LOVE to travel
3. More one-on-one time with our child
4. No sibling rivalry or fighting
5. More time with my husband at night
6. Easier to focus on one child's homework at night
7. We only have a two bedroom house :)
8. Saving for college will be easier
9. My husband and I never have to "divide and conquer" as I see all of our friends having to do w/ their kids
10. After nursing for 21 months, my boobs are still in pretty good shape. Doing it again? Forgetaboutit!!
11. I have the energy to play with our daughter!
12. Every little thing is special w/ our daughter :)
13. Family is very willing to watch one child while we have our adult time. Two or more? Don't think that would happen.
14. We honestly couldn't afford another child, whethere we were up for it or not
15. For us, one child is easier on our marriage
16. We're the 3 muskateers and a really close family
17. I never have to go through infancy stage again!
Good luck!! ;)
