5yo cries every time she doesn't like something

[longestlurkerever]

Dd2 is generally the better behaved of my dds but bursts into tears every time she doesn't like something and it's really starting to grate on me. Things like I tell her she has had enough screen time, or she has to eat some vegetables or we are walking/cycling somewhere rather than driving, or (worst of all) over anything competitive like a board game that doesn't go her way. She wails and cries till she's red in the face and curls up in a ball. I'm afraid I don't have much patience with it but am also at a loss how to get her to stop. I mentioned a lack of resilience to school but they say she's fine there. I think lockdown has made things worse, as things like a trip to the park are greeted as if I'm torturing her. Advice welcome.

My just gone 5 year old is similar.
Reacts by crying & whining to most things they don't want to do.
I don't know if this is normal, it's certainly wearing me out.

I train a behaviour support programme and we explore the 'window of tolerance' first mention by Dr Dan Seigel.
The concept is we are born with a narrow window of tolerance to distress such as hunger and being left alone. As we grow, we learn tolerate more when stressed out etc. Adults continue to have a window of tolerance when feeling stressed - some are wider than others. My window is def narrower than my partner!
I explain more about this concept in my article about attachment as they go hand in hand.

The crying might be your child's way in coping with her feelings. The trick is so validate the feeling, co-regulate to teach a new way to behave when feeling that way. My 4yo responds really well to this way of parenting. My 2yo pushes my buttons and requires far more patience when trying to co-regulate but we'll keep trying!!
good luck
