Daughter throws fits wherever we go, in the store at a restaurant ect,. turned 2 two months ago,, what to do?

Schedule your grocery shopping after DD's nap so she is well rested, schedule eating out at a time that is not close to bedtime and verbally reinforce appropriate behavior looong before you arrive at the store or resturant. My DD was around that age when she threw a ginormous fit in Target. I told her that if she continued to scream, we were going to go straight home and go to bed. She continued to act out, so I left my cart, drove straight home, and when we walked in the door, she said, "C'mon momma, let's play!" I said, "No ma'am, you are going straight to bed for screaming in Target" She was so upset, but now, I prepare her on the drive by saying, "Now remember, if you scream in Target, you go home and go straight to bed" She hasn't done it since. She's 3 now, and if she hears a kid screaming in Target, she'll say, "Momma, no screaming in Target. He/She should go straight home to bed!" LOL!
