Where do you think Victoria was born then, bearing in mind that her birth must have taken place before her parents left the burning car on the M61 in which a placenta was found?I don't think she gave birth in the cottage. There's no mention of any blood or fluids from the landlady when she went back there. No way they managed a hole birth without staining any towel, sheet, mattress, flooring, or meticulously cleaned up all trace. Then proceeded to re-trash the cottage in the next couple of days and leave.
It seems they have very poor hygiene and trash every place they live. Even if they intended to conceal it, I can't see them being so thorough thorough there is nothing to indicate it and they got rid of all resulting rubbish.
I think they want to say she was born there because it was the 'nicest' and most stable environment they'd been staying in around that time. They are trying to keep her lifetime to when they were still staying inside. It makes it somewhat easier for them to argue she didn't die of negligence and neglect due to her living conditions if she didn't die in a tent.
Another question is where and when the prosecution will say she was born, or whether they will even present a narrative on that score. They are saying they dispute the defence position (at least stated to the police, not yet in actual defence) that she was born on 24 December. No alternative date has been put forward, though, even an approximate one. But it's not the defence that has brought a case or is required to bring any evidence if it chooses not to. It's the prosecution. It's going to be interesting to see what evidence they can bring to support various of the statements made in the prosecution opening speech - poor hygiene, Lidl, and Travelodge, or no poor hygiene, Lidl, and Travelodge.
