Angel_eyes if you take your daughter on the bike, make sure she has a helmet, if she sees you with one it will make it a lot easier to get her to wear it.
Have you considered a bike trailer for her? They tow quite easily, and I think are much safer than the seats that go on the back of the bike. They all have a device on the hitch that will keep the trailer upright if you fall or lay the bike down. She should still wear a helmet, though.
I just started my grandaughter in the trailer a couple of days ago on short rides, and it's worked out great.
Good luck!
