A friend of mine is still bfeeding her 15 month old (despite being in a peer group of mums who stopped at a couple of months), but is concerned that she won't be able to get pregnant if she continues. She wants to try for her second baby now because she is already in her late thirties so doesn't have much time. I know natural child-spacing uses bfeeding as a delaying tactic but i've also noticed a lot of moms on MDC who are nursing AND pregnant. I would like to encourage my friend to continue if she wants (and her daughter clearly wants to!) but i can understand her concern about it affecting her fertility. is there any research anyone knows of, or personal experience, that might be helpful? Her daughter isnt very keen on solids and eats not much other than breastmilk, which concerns her at her age. She is quite little but not underweight.
