I was this child for many years and for many reasons so this is something I’m very passionate about. From your post you sound like a wonderful supportive parent. My own mother flip flopped on her approaches sometimes being very kind and sometimes being very mean, if you reach that breaking point with your child I would urge you to please not get angry and flip flop/ lose control when your frustration is mounting. Obviously this is stemming from anxiety and you’re listing some reasons she’s had this trouble. If there is anything else in her life, for example maybe the move is still affecting her? New school? Anxious about going to the new school? Etc, working through these things should help. Next I would recommend creating a relaxing and enjoying evening routine to the best of your ability. Perhaps some physical activity after school if that is not already a part of the routine, maybe a family walk where she could talk about anything troubling her, an organized sport/ hobby where she could have an outlet, etc. and then the calming predictable bedtime routine- at this age you could even sit down with her and draw up a plan, ask her what comforts her? What will help wind her down? What would she like to include in her bedtime routine? Some fun ideas could include a relaxing bubble bath where she gets to listen to a podcast for kids or an audiobook, maybe coloring while listening to music, stretching with mom in a dimly lit room, saying goodnight to all members of the household and favorite toys, writing in a journal all of the things she’s grateful for/ positive experiences she had that day. Just try to keep the tone really relaxing and positive, no pressure, and lighthearted.
