2.5 Year Old is Unruly in Public.

I'm not usually the type to seek advice from strangers but It's starting to get to the point where I think me and my wife could really use some help.Whenever we take my daughter out in public shes just... terrible... and I don't understand why. I dread taking her out to eat because 90% of the time she screams, cries, and tries to run around the restaurant.I was in a store the other day and as I was talking to the salesman I was holding her and she when she started screaming, so I just told her to hold on a minute and that I was busy, I guess she didn't like that and she actually ended up hitting me in the face in front of the salesman, needless to say it was pretty embarrassing. I have no idea how to punish her, I feel terrible yelling at her and when I do she usually just laughs.The other big issue we have is bedtime. It's always a HUGE fight to get her to sleep, it usually involves a lot of kicking and screaming until she basically falls asleep while crying.I don't know if this is enough information for anyone to offer any advice but if you have any question feel free to ask. It's taking a toll on me and my wife and I'm desperate for help. via /r/Parenting http://ift.tt/2gqk2DN
