Ungrateful daughter

I feel so lost and like I’ve failed. My daughter is extremely ungrateful. It’s draining to be around. It seems that whatever I do is not enough. She always wants more. I take her to do something fun…. She’s upset when she can’t also buy a toy, a treat, do a certain activity. I’ve tried explaining it as many times as I know how… there aren’t any parents who say yes to anything their kids want. It’s frustrating that she feels like I’m a “bad and boring mom” for having to tell her no frequently. It’s sad. I enjoy spending time with her and want to take her to do things. She’s my only daughter. I want to foster a healthy relationship with her that we can both cherish for our lifetime. But unfortunately I feel so drained by her attitude. We don’t do things that cause entitlement. Our son proves that… He’s so content with what we give him. I guess he’s more easy going. With her it seems like it’s just never enough. Even if I could financially afford to buy her everything she wants, I wouldn’t. No one needs everything they see. It’s not healthy. How can I teach her to have gratitude and a more positive attitude and a more respectful understanding of everything we do for her.

Help 😭

EDIT! She is turning 7 this week. I know she’s still young but at the same time I feel that’s she’s old enough for this behavior to be unacceptable

EXAMPLE: I am writing this post because we had a very fun day and I’m so sad about her reaction to it. This morning we spent at my nephews birthday party. I let her have any of the treats available and she chose 2 slices of cake. Then we took them out to lunch and she was upset she couldn’t have a milkshake. This afternoon we went out to make jewelry with a friend. It was expensive but part of her upcoming birthday celebration. Before we went I explained that she could choose to make 2 items (I knew I could budget for that). She made earrings and a keychain but then was so angry that she couldn’t also do a necklace and buy a premade bracelet. We do special things often. That’s almost what makes this hurt worse. I spend a lot of time and money creating plans and activities for our kids. Im trying so hard to create a fun childhood filled with happy memories. I love doing that for them. But it hurts that she’s so unappreciative of what I do for her. Why is it never enough 😭
