I recently had my 9 year old son diagnosed with high Aspergers. I have a 2 year old daughter (28 months) and here are the things she has obsessions with:
Directions... She knows exactly where we are going in the car without being told
Colours... She knows them all
Lining things up such as books and ice poles out the freezer and stacking her Mr Men books and DVDs
Her speech is not as good as other children born close to her age
When she is upset no one is allowed to go near her or enter her space
She can draw things like flowers and mice
Obsessed with watching tom & jerry and laughs when tom gets hurt
She is advanced physically and can climb and do things as good as a 4 year old
Obsessed with possesions and has to say who belongs to for example as I put washing on the line she likes to tell me who they belong to
Lokes to play alone at baby groups and if any other child gets close to her she cries
Refuses to try new food and will only eat when she has discovered in the last year

I also believe as a child I grew up in the world with these problems and went through life undiagnosed and lonely and I don't want my children to be the same.
I was lonely, had no friends and thought they were all nasty for not wanting to play with me so I beat them all up.
My daughter is like my son in many ways but are both weird in many other ways

I'm finding it hard bringing up one child with this and don't think I can cope with a house full of ASD kids. I have a 1 year old daughter too and hope she does not have it or I'll go crazy!
What do you think?

She might just be a very smart little two y/o and a future Mensa member.

Don't knock Asperger's. I'm married to one, his dad was one, and my older son is hyperlexic (another form of autism) and a much-valued library employee. Some of the best and most conscientious and FUN library volunteers I've supervised were Down's and Asperger's. (Libraries are great places for Aspies to be!)

Have fun with your daughter, and let her teach you how to play. Make games of her "obsessions," and give her a chance to grow up a little without forcing playmates on her. Allow her obsessions to help her learn so much about so many things.

I know this is not much good to you right now,but I'm a job coach for people with intellectual and phyiscal disabilities.
Currently I am working with 2 adults one 19 and the other 24 with asbergers /downs. Both work and lead very full lives.
There are many training methods available some that are accredited,and some that are frowned upon.
There are also a lot of cogitative therapies that work really well,and could make your day easier.
I will say this though,there are so many schools of thought that you would need a trained therapist to teach you.
