AC there is no court on this earth would accept something snagged from the baby for DNA tests while the child is alive. (hair brush, baby bottle, etc).
A court is going to have order that a DNA test be done and that it is done legally with proper procedures so that there is no arguement of how the DNA was taken from the baby.
True, but it wouldn't stop Birkhead from proceeding by himself to prove it is his daughter he is fighting for... just for his own peace of mind.
