She is 3.
They get like this.
It is a hard age.
They like routine.
They are becoming a 'big kid' but are still 'baby' and maturity wise... they are still developing.
They do get like that.
Does she nap?
Tired kids, ALSO act like that. They have no patience and get irritable.
It is also a personality type.
Some kids/people just being more routine oriented or others being more adventurous.
One way, to assist... is.... BEFORE you go and do anything, prep her about it first. Meaning, talk to her about it, what she needs to do to get ready, explain where you are going and why, make the 'process' of it.... tangible to her. Not just all of a sudden.
Some kids... simply NEED to 'transition' to things... first. By getting a head's-up about it, first. Before the said activity, is going to happen.
But if it concerns you, maybe talk to your Pediatrician.
But to me, she is simply acting like a 3 year old.
Or, maybe, like many young children, they simply get overwhelmed with all the 'choices' they have.... and expectations on them.
But if she never wants to leave the house.... and it does interrupt daily living... then well, maybe she is having a hard time... with that.
So then, talk with your Pediatrician about it...
