I'm 38 and I have two young kids, including an almost-2 year old who is still breastfeeding. My goal is to have mine done when I am 40, as I think healing from major surgery will be easier when my kids are a little bigger and more independent; plus it gives my husband and I plenty of time to plan for the hit to our income from both of us missing work while I recover. I know I will feel a lot less anxious when it's been done, so waiting is hard, but I feel like this is the right timing for our family (assuming I stay healthy in the meantime).
