I've seen so many posters wobble about whether or not to try for a 3rd. The advice always seems to be 2/3rds hell no (really hard, increased risk of SEN etc), 1/3rd yes it's tough but worth it. My circumstances are- approaching 40, 2 DC, always wanted 2 DC but can't stop thinking about another baby ever since younger DC turned 2. I'm telling myself to ignore it, blaming my hormones etc, but I can't stop thinking about how lovely it might be. I'm thinking I just need to wait this out but but...what if I regret it?
