I have 3 children, 9, 13 and 1. My 1 year old was part of a twin pregnancy. One of my twins died before birth so is registered as being stillborn. I only claim for my 9 and 13 year old as my 1 year old is my 3rd baby. After a discussion with a friend she thinks that maybe i would be entilted to claim for my 1 year old as he was still part of a twin pregnancy. Cant find any information about this online. Thanks in advance for any advice.
