I have no idea. We're trying to make this decision now. I'm doing ecological breastfeeding too, but my fertility returned at 6 months (it was intermittent at first -- came when I was spending a lot of time with my sister, and in cahoots with her cycle -- but I've been regular for several months now). Simon is 19 months now. He's still an avid nurser. The thought of him trying to nurse and not being able to get any milk, or finding a tiny amount of not-so-tasty milk breaks my heart. He's also a very picky eater and I'm sure that the breastmilk is still sooo important to him, nutritionally speaking. He's been slow to develop an interest in solids and I don't want that forced on him because I'm no longer able to help him meet his needs. There are practical reasons we'd like to try to have #2 sooner (might be moving from Canada to the U.S. soonish and it might make sense to have the baby here to avoid the healthcare issue in the states and having an American baby [technically speaking]-- not that there is anything wrong with that
, but we're Canadian).
The more I hear about difficulties with 3 year olds, the more I think of putting things off. But then we'd be starting fresh with all of the toddler stuff again, which is fun, but also very taxing. It seems like it might be nice to have our children closer in age so that they'll be closer in their interests and abilities.
Who knows what will happen. We've been changing our minds every other day. I guess that all it will take is for us to be pro-baby-asap on a particularly frisky day that happens to be close to ovulation.
