Hi, we're in this boat too. DD is almost 3 and we just simply can't afford to do fertility treatment again plus age has caught us up too. I constantly feel like I'm denying her the right to a sibling. I've had the 'will you have anymore' question a few times and am trying hard to not answer with my usual short 'probably not' and rephrase it into 'sometimes these things aren't in our control'. DD is a great kid ... We just focus on the benefits being a family of 3 means to us.
