I was sleep deprived with my first child, now 10. She was formula fed and slept in her room in a crib.

With my second, I had learned a lot more. He was breastfed and co-slept. I was STILL sleep deprived.

The amount of sleep you need vs the sleep needs of a baby mean nothing. Having a baby, whether you breastfeed & co-sleep or not is going to lead to broken sleep. Not something easy to deal with when I was 25, I imiagine it wouldn't be any easier at 40.

And yes, there are tests that can check for downs. So if you get pregnant one, two, three times, whatever, what would you choose to do with that baby? Doesn't seem as easy a choice to me as you are making it out to be.

Having a baby is hard at any age. Having a baby at 40+ is most likely NOT going to be a walk in the park as you make it seem
