our Ds was 12 when we started IVF and he got so worried as to why i was going to the Dr's all the time. We should have told him earlier. I would tell your DD the truth -perhaps find a book to explain it. I will google it or ask on other IVF forums .

Maybe she is scared something really bad is wrong with you and she is scared of losing you. Maybe tell her Drs are doing some tests to help you have a new baby. Tell her you are 'well' but you and daddy need Drs to help you. Tell her about the injections - it is not because you are sick but to help make your body get ready to make a baby.

You need to ask yourself is She is old enough perhaps and ? mature enough to deal with it if you don't have success the first time. Maybe don't tell her all the exact details like when the transfer is and the TWW , blood tests exactly but do say is all part of the Drs plan and you will tell her first when you are having a baby. She might pick up on the stressful time anyway.

In mean time explain these special Drs /hospital visits are for well mummies and daddies who just need some help to have a baby.
