Ok this might end up being kinda long, so my apologies. some background on kaydee, she is 3 1/2 will be 4 in jan, and im starting to wonder if she may have some sort of mood disorder. she has some strange quirks that ive been trying my best just to deal with but now im wondering if she got some sort of a diagnosis and we could find some sort of therapy for her it may help, or at least i could learn the correct ways to cope and help her. She does not sleep well, and wakes often. she has trouble going to sleep at all and usually will not go to sleep until she passes out from sheer exhaustion. she does not take daytime naps regularly, but will sometimes on occasion pass out while playing or watching tv (and then be up all night ). when she does finally lay down to go to sleep she will bang the back of her head repeatedly against the headboard, to the point that if her bed isnt up against the wall, she actually forces it backwards until it is pressing against the wall. shes been doing this for as long as i can remember and used to move her crib around the room when she was a baby/young toddler by rocking on all fours banging her head into the bars. she gets very angry and throws MASSIVE tantrums over the smallest reasons, if she doesnt get her way on the smallest issues. when she does this, she screams about how no one is her friend and she doesnt like anyone and will shut herself in her room and bang her head against the headboard or wall. nothing i do stops this and if i interfere it usually gets her more upset, to the point that she will scream, hit, throw things. if i leave her alone, she will scream and bang her head until she eventually falls asleep. she doesnt like to play with other kids her age, and when at a playdate with kids the same age as her, she will make friends with their parents, refer to the parents by name, and as her best friends. if asked if she would like to play with the other children, she gets upset and will usually cling to me. she will play with older kids if given the chance, but they usually arent interested in playing with a 3 year old. When we go to playdates with the same kids over and over again, she remembers all of the parents names and talks about them after we go home, but doesnt know who im talking about if i refer to the other kids by name. She is very upset by any changes in her life. she attaches herself to people (adults), and if she doesnt get to see them anymore, she gets VERY upset, crying hysterically and eventually getting angry. she cannot handle loud noises unless she has been warned in advance so she can hide and cover her ears. if someone starts a car or motorcycle near her and shes not prepared she will scream, cry, and hide. once a lound motorcycle actually woke her from a sound sleep and she wet the bed (only time shes done that!) and was hysterical! she is very manipulative for her age, and will back talk and actually come up with a way around punishment if given one, such as if the TV gets turned off for bad behavior she will turn it back on or plug it back in unless it is actually removed from the room. or if i say she cannot have something she will purposely wait for me to leave the room to ask her dad or grandma the same thing hoping they will give it to her. (is this normal for a 3 year old, i thought backtalk and manipulation were traits of much older children?) on the other side, she is a VERY sweet loving little girl, she is very bright for her age, has the vocabulary of a 5 year old, knows all her colors and shapes (including all the weird ones like pentagon and octagon), counts to 15 and can even count down from 5 and is very very imaginative! she tells me stories she makes up in her head, has imaginary friends at times, and goes on imaginary trips that she tells me all about. she is very artistic and loves to draw and paint (scribbles lol), and loves to help bake and cook. shes very sensitive also and takes everything to heart. if someone is yelling she assumes they are yelling at her and asks what she did wrong... i think i am going to go to her pediatrician and get a referral for an evaluation from the behavioralist, but i guess i just needed to get all this out and if anyone has any similar experience or input it would definitely be welcome!
