What is your tone of voice when you tell her to do X and again when she doesn't do it and you reprimand her?
Sounds like this is a new rule that you will only tell her once. That is unreasonable for this age. I like AV's suggest to make lists. This way she knows two ways by your asking and by the list.
Her brain is still very immature and it is difficult for a child that age to remember what she's to do. They're also impulsive and want to finish what they're doing before doing the new thing. But then they don't remember.
I suggest that you tell her once and then remind her a second time. You can be strict without being harsh. Be sure your voice is relaxed in the way it would be if you expected her to follow thru. It's so easy to be tense in situations like this. We want to see change quickly while in reality all change is a process that may take weeks to form the habit.
I also urge you to give her 8 compliments for every criticism. We all thrive on compliments. They also make us feel that we are good which makes us better able to get with the program.
Do you make a point to spend fun time with her every day. You have to share happiness for her to feel loved. When it' possible include her in doing chores with you and have fun doing them. Also give her choices when appropriate. You don't say what x is and so it's difficult to come up with an example.
Also do you make chores fun? One example I've seen several times is to set a timer for everyone to pick up a room/put their things away. Make it a contest to see who can finish first.
Show her a lot of love. Give her lots of hugs. When you hear her crying go in and talk with her. If she'll let you give her a hug and tell her you love her. Just listen as she tells you how she feels. Do not try to justify your rules. This is a time for her to vent and release her feelings. By allowing her to vent while you're treating her in a loving way will help her feel loved.
Talk about the rules well before bedtime. Another idea is to make a list of things that need to be done that are appropriate for her age and let her choose what she wants to do. Decide together when she'll do them. Perhaps make a chart so that she can mark the chore off when it's done. this will help give her a sense of accomplishment. Praise her every chance you get.
What activities are you cutting back on? You're cutting back on company too. Is this for discipline? I suggest that at this age the consequences need to fit the situation and should be short term. For example if she doesn't get her chores done it's reasonable to say she can't have a friend come over the next day or the next opportunity. Also give her ways to earn back the activity or company. In this example if she gets her chores done the next day then she can have company again. You can also say that certain things have to be done before she has the friend over or is involved in an activity.
One of the difficulties in parenting is finding a balance between teaching responsibility and allowing them to be children. It does get better once you find this space and are consistent in your expectations. Praise, hugs, and happy times together are an essential part of this.
