I had my third at 41. She will be 2 tomorrow. Sigh.
I would have three more if I was younger. But we decided to stop, and both of us would have three more, btw!
that baby at 41 was much harder than that baby at 39. The sleep thing is a killer, and then you have another person making demands. It can be a bit much if you are tired. I don't even know if I could handle two less than three years apart again. I was so happy my son was 3 when baby came along. He could get himself in his car seat, straps and all. He didn't need me as much, and it made things so much easier to just focus on baby. With the first two, they were so close in age it was hard.
Lots of women do it. I decided for my overall well-being, it was time to stop-and I am a very young almost 43 years old! Toddlers are exhausting. To be 41, pregnant, and chasing a toddler? It will be hard, but with the right self-care practice, possible. But you will need a lot more self-care, and you'll need to make it a priority.
