I can't shake this feeling but it categorically isn't a good idea. We have a DS who is 2yo 10mo and a DD 10mo. I've got a kidney condition which is degenerate and this is sped up in pregnancy. I had very medicalised pregnancies, 2 inductions, x4 consultants etc. Everything was fine except I lost kidney function as predicted. I really want another baby but I'm basically bringing forward my need for a transplant. To add to this I got awful PND this time and my relationship has been tested to the max due to my husband going through a life changing trauma. On paper it's such a bad idea but there's one more in my family ideal.....
