Only one ticket per member for Liverpool which is frustrating as I wanted to take my daughter to that match as I think it will be a more entertaining game than Burnley which is the only other game of the three I can make. Even if I joined my kids up for bronze membership I couldn't guarantee that we'd get seated together as I'd have to buy the tickets separately. Going to be same for the other big teams I guess.
No need to purchase separately; add your daughter's Young Seagulls Plus membership under Friends and Family. Then add 2 tickets to your basket and assign 1 to her before check out and you are good to go.
