The mother of conjoined twins says her girls are very much determined to be here.
Hannah and Dan Bateson - from Toomebridge, Co Antrim - welcomed Annabelle and Isabelle in March.
They were born via C-Section at University College London Hospital.
The girls are joined from the chest to the pelvis and share a liver, bladder and bowel.
Hannah says they were so happy their girls were healthy.
"Our big concern was we fully expected to have very, very sick babies when they were born.
"There was teams prepared for ventilation.... that they might not be able to breathe on their own.
"Our big prayer was that they would be born crying, and both girls came out with heads of black hair and screaming the place down.
"We just keep talking about our wee miracles and just how determined [they are].
"Whatever it is they're really, very much determined to be here".
The family will travel back to London shortly for more planning for their separation surgery.
Hannah says: "We actually have a lot of that still to do, we're due to go back over shortly actually back to London - to Great Ormond Street - for a lot more detailed imaging.
"So that the surgeons then can plan as far as they can. I think a lot will be just be discovered during the surgery".
