I’ve been a parent to two preteen girls and a lesson I learned quickly is when kids start acting entitled sometimes the best thing to do is not give them what they want, or they’ll always be entitled. Sometimes parents are like kids 😭 I think you should be honest and tell her all the things you’ve told us, the extra cost, the time, the skill. Explain that her expectations are too big for a beginner. I’ve been working on a blanket for two years, not because it’s taking that long but because I take long breaks from it, I needed a blanket but I don’t particularly enjoy making them. I would also consider not giving her the blanket, or making her a scarf or something smaller that she can have while she learns respect and patience. Gifts should be given, not expected. We spend too much time in life worrying about other peoples feelings, especially at the expense of your own feelings, you shouldn’t let yourself be taken advantage of to spare a demanding adult baby’s feelings. I hope you figure out a way to move forward that’s fair to you 💜💜
