I'm fed up, tbh, she never seems to listen or take no for an answer, and she just bosses me around.
She'll say "I want to go to the park!!" To which I answer " we can go after I've done X" so the whole time I'm doing X she'll keep going on and on about wanting to go to the park. Drives me mad, because I've already answered, with a visible time scale (usually it's either needing to do the washing up, or changing a nappy) and by then I don't want to do what she's demanding (although the frustrating thing is that the park is pretty much the only time I'm not bombarded with questions and orders or having to stop fights between the DDs)
And when she asks a question and I answer, she'll then argue with my answer. Honestly it's exhausting, and my patience is completely gone by 8am every morning. So I then spend the rest of the day getting more and more angry, cue loads of screaming, which obviously don't help!
So how do I get her to understand my answer is finally? I'm thinking of implementing a "if you ask me one more time after I've answered then the answer is no" but that won't help as she'll just have a massive tantrum.
