3 year old personality disorder??

[itsmandy24]

My 3 1/2 yr old daughter seems diffrernt than others her age. Shes very smart and remembers EVERYTHING (Points out stores we went to one time years ago; can point out shopping centers from behind from the freeway, etc). Shes very hard to appease when answering her questions with a simple answer and explains her thoughts using reasoning (EX.: she asks why she has to sit in a carseat- I respond "because I said so"- she says "no, its because if I don't a policeman will yell at you." She makes it very difficult to drop the current subject to another one easily lol.
She is also very advanced in language and uses words like "actually", "probably", and "imaginary". Her teachers at daycare LOVE talking to her and people in public are amazed when she speaks. She can even spell several 4-5 letter words and recites our address complete with zip code!
On the other spectrum though, she doesn't ever seem to find anything funny, and even fakes laughter in a situation where her peers are amused. As an infant, she laughed maybe once before her 1st bday. Instead, she'd deeply study whats going on like she knew my funny faces (for example) wern't actual expressions and were just a pathetic attempt at getting a reaction from her.
Is this all normal??

Perhaps since she is so advanced her humor is also advanced.

Normal for her extremely advanced mind. She is brilliant, obviously, and she sounds normal, more advanced then the mass majority of children her age, yet normal. I wouldn't worry. Take joy in your advanced child, and try to find other parents with advanced children and get advice.

Haha thanks for the reassurance. A key factor in my worry though that I forgot to mention of is that I have bipolar d/o and depressive disorder and I see so much of myself in her it scares me, but I could just be reflecting my own flaws in her unfairly.

Consider talking to a counselor or psychologist (you'll have to do the research to find out what kind) just to reassure yourself there is no mental health disorder in your child. They might be able to answer your questions and quell your fears. Also, if they do take time with your daughter, they could do annual follow-ups just to ensure she continues to develop as expected.
