passport signing below the line

[hawkins9913]

hi all,
my daughter just received her first adult passport and has signed below the line, she thought it would be a fantastic idea to sign above the line as well. we are meant to be going on holiday soon, and are worried if this makes her passport invalid? or will she be ok to travel ?
thank you

I think this has been posted on the wrong topic but I wouldn't worry too much about it. As long as it has been signed.
