TTC after baby?

I agree with the previous poster. I wouldn't choose not to breastfeed just solely for the small possibility you might be more fertile right after the birth. Some people are more fertile and other people still have the exact same fertility problems that they had before. Some people even have a harder time getting pregnant with their second than they did with their first. I think it is too much of an unknown factor to choose not to breastfeed just for that reason alone. Even while breastfeeding your fertility may return. I personally start getting my period again within a few months of birth even though I exclusively breastfeed.

This is a tricky question. I have also heard that some people are more fertile after having a baby, but I wouldn't hedge on it. What would concern me more than anything if I were you is your age associated with the problems you've had getting pregnant. Those are the greater factors I would weigh. The only reason I word it like that is because my dearest friend is also going through similar unexplained infertility treatment and I know every doctor has mentioned the success rates for infertility treatments drop off sharply at 35. If you are absolutely positive you would like to try for another I wouldn't fault you for wanting to not breastfeed. It is like all things and effects women differently. For me, the whole time I was BFing I was infertile. It was absolutely a natural contraceptive to me for the entirety of 9 months until I stopped--even though we were doing solids as well. I wouldn't not breastfeed because you think you might get pregnant in a more fertile time period after baby gets here because that is debatable. However! Given your age and previous issues I think those bear some serious thought on what your decision might be. It's up to you! No one will look at you any better or worse for what you do. I've BF one and FF one and I will be the first to tell it is all different depending on your child. There are benefits to BFing (such as the child not getting sick as much, etc) that aren't necessarily true for each child.

What a difficult decision! I haven't heard about a bump in fertility immediately following birth, but I have heard about a lot of women who are much more fertile after they finish breastfeeding.

I didn't get my period until DD was 13 months old. Then I only had one and was *BAM* pregnant again. With our first we tried for about 6 months (with charting, temps and trying to do everything the right way.) Because it wasn't super easy the first time around we weren't thinking about contraception. I felt a definite boost in my fertility when DD started sleeping through the night (12 months, then got my period) and I had another boost when she was down to 1 BF a day.

I think it would be a good idea to start off BFing and see how you go. I think docs recommend waiting 6 weeks before having sex anyway, and even if you only BF another 6 weeks after that, it would make a huge difference in getting your baby off on the right start and give you that wonderful bonding experience.
