She's only 8 months. It's totally normal for a healthy baby of this age to wake unless they've been trained (which is detrimental to their physical and mental well being in the long run even if the results seem convenient at the time).
Personally I cosleep with mine, best way to get sleep, get the night feeds in and if done safely adhering to the guidelines issued by UNICEF believed to be the safest place a baby can be. Contrary to popular belief it doesn't spoil them and they do eventually want their own bed and sleep through with no stress
Self settling is something that comes with age, just like walking, talking etc it's a stage the reach when the parts of the brain required to do this have wired up. When this happens just depends on the child. We all wake at night, just takes a bit of time to work out how to get back to sleep without comfort of another.
This stage of their lives is short compared to the rest of your life, thos quiet unhurried nightime cuddles are to be cherished, you soon miss them once they've gone.
You also often find night wakings can increase when they get older as they are so busy and active in the day they "forget" to feed and need more calories for all that activity and growing, they want to catch up later when it's boring.
If your babies sleep habits really do bother you why not try The No Cry Sleep Solution by Elizabeth Pantley for some more gentle ideas they won't cause stress and long term problems like other harsh methods can. I've also heard good things about Dr Jay Gordon's idea but I believe he does think under 1 is too young to start trying to change their sleep habits.
