Trying to conceive in 40s while still BF toddler - should I wean?

I'd see if you can get your prolactin level checked. If your LO is 2 1/2, it's probably normal, and nursing isn't interfering at all. The only thing that might alter that would be if you're still doing a lot of night nursing. They do say that rare women can't get pregnant while nursing, but my thought is that you'd also be experiencing issues with ovulation, etc. I've never found anything that specifies that, though, so it's just my guess. I think a lot of OB's don't have up-to-date info on ttc and nursing, though.

I'm 43, and got pg while nursing my then- 23 month old 6 or so times a day, and still night-nursing. I was planning to cut back a lot when DD turned 2, but got my bfp about 5 weeks prior. I do have a theory, though, that at our ahem...maturity level....it's harder for our bodies to recover from pregnancy/baby-rearing/night nursing, etc. I found when I started really focusing on getting enough sleep, eating my optimum diet, and also increasing my fat intake, it happened. I also read The Infertility Cure, and started doing the acu-pressure that she recommends in there about 2 months before I conceived.

I guess, for me, weaning was something that was on the horizon as a possibility, while ttc, but, I always felt like there were other things I could try first. I also felt like, if weaning didn't work, then I'd have a weaned-early (for her) toddler, and no baby, anyways, so it was my last-ditch thing, if that makes sense....But, everyone comes to their own decision with that, and it just has to be right for your family.

I'm sorry for your loss, and I hope you get a nice healthy pregnancy started soon!

Thanks everyone for the great responses!

Buzzer Beater: I've been charting temps and also doing over the counter ovulation tests, and gotten positive tests along with the temp dip when I've been good about charting and testing. Right now we're nursing upon wake up, then usually at pick up from daycare, and maybe a couple of little "sips" until bedtime. She's nightweaned now for about 7 or 8 months.

Sundaya: Can I get a big AMEN on it being harder for our bodies to recover from pregnancy/nursing/sleep deprivation! I felt the worst I've ever felt in any pregnancy in the last one and that was what led to nightweaning. Now I think I'm still not paying as careful attention to sleep (always seems like night is only time to get important things done since I work all day) but I probably do have to give that up even more to give this the best shot I can. So how do I test prolactin, and can I do it or a regular OB do it, or does it have to be an RE?

Dejagrw: I have been charting and it *does* seem like my luteal phase is shorter now than it was pre-pregnancy. I wasn't sure if that was my age, nursing, something else, all the above... Do you know any good websites that simply explain what a "healthy luteal phase" or "normal luteal phase" is? I also notice my period comes every 26 or 27 days now, where it was iron-clad 28-30 for my whole life until pregant with DD. Are those bad signs, anyone know? And yes, I would be a bit sad to wean and then not get pregnant, but more because I just think DD will not react well to weaning and I hate to put her and I through that. But for me personally, I'd be fine with weaning, I feel like we had a great run and it would actually help my relationship with my DH a bit if I did wean. But that's another thread...

Kittykorat, congrats on the suprise pregnancy and thanks for the hope! That's great news, and good to know you were nursing the whole time!
