YES~ And this morning I found out I am pregnant with my third! I keep crying because I am so happy.
I got rid of all my baby stuff when my second was 6 months old. Then when he was 9 months, I started to regret it. By 12 months I was obsessed with the idea of a third, and I then spent the next year going back and forth about whether we should do it or not. My youngest is now 2.5 years old. I literally spent almost 2 years fretting about it!
I turned 40 last month. Best thing that could have happened to me! I realized that life is too short to live with fear. There are NO cons with having another child. The more the merrier, you will always find a way. Stop weighing your options. What does your heart tell you? If you at all feel a pull, I say GO FOR IT. No one ever regrets having more children.
As to giving your children attention, have you ever spent time with large families? The kids give each other attention! I am sure you know this with your boys so close in age. Just think how easy a baby will be with two little helpers to entertain it!
You have so much time to decide. You could do what one of my friends is doing, she had two girls close together in age, and then they are waiting 10 years and will be having another two. She figures they will have more money, two free babysitters, etc.
