Fetal Heart

My baby was diagnosed with DORV, Tetralogy of Fallot and right aortic arch. I am back and forwards between two hospitals for the remainder of my pregnancy so they can monitor him and his heart. He will require open heart surgery. I was wondering if anyone is/has been in a similar situation and can give me a bit of advice on things such as Labour, if his heart remains the same and it doesn't deteriorate am i more likely to be put on bed rest before his due date etc? any advice appreciated. thanks xx
