Nothing you describe would lead me to think your daughter displays any condition along the Pervasive Developmental Disorder spectrum, including Autism. Releative to her gait, have you had her evaluated by a pediatric orthopedist? It is important to determine if her bone structure and connecting tissues are developing in a normal fashion. Relative to the other behaviors, while they may be indicative of some anxiety, they appear much more to be developmentally-related. Adhering to particular routines, structures, preferences is not at all unusual in a child of two, and I expect you are going to see more adaptability and flexibility as she grows and develops.
It is very simple I think, milk allergy has never resolved completely. May be she has negative blood tests, but you know there is something called type IV allergy which means that she might react with T cells to the allergen. It is possible that she has constipation, or at times diarrea or pain in the abdomen. Help her by eliminating casein, lactose, galactose, lactalboumine and milk protein from her diet. Anyway you can search in the Internet where you will see that consaltants on Autism suggest elimination diet for the patients, of milk products and gluten.
Hello. I am the parent of a 5 1/2 year old PDD-NOS girl, as well as a service provider. I would suggest you call your local County - Department of Health, Early Intervention program. Early Intervention (EI) is a Federally Mandated, State Funded, County Managed Program. What Early Intervention will do is (this is how it happens in NY anyway):
1. Talk to you to determine your concerns
2. Send to your home an Intake Service Coordinator (sign some paperwork about allowing them to test, etc.).
3. Set up a Core Evaluation with an agency of your choosing
4. The core will most likely include a speech language pathologist (because of your "repeatitive use of language concern"), occupational therapist (because of your "limited eating/texture" concern as well as other sensory concerns "the blanket")and possibly they will bring a physical therapist...or after the initial assessment will recommend a supplemental evaluation by the PT.
5. As soon as they finish the eval, they will give you their recommendations. They will advise if you should go to a developmental pediatrician or not, and what services she qualifies for.
It is good that she is using language and is affectionate. If she makes good, consistent eye contact and turns to her name, then you are in good shape.....I'm not saying you are totally clear, I can't say that....but I can say, at 2 my daughter had zero words, couldn't maintain eye-contact EVER, and didn't turn to her name EVER. She had perhaps 5 percent understanding of language. I stood behind her clapping, calling her, and she didn't even flinch....I thought she was deaf, and I'm an audiologist (professional pediatric ear chick).
Many children use repeatitive movements/songs/words as a self-calming mechanism. Especially when they are just learning about the rules, etc of language...they will practice a lot. Catagories are especially important as they order their surroundings.
Your intuition is very important....so, call EI. It may be nothing...but don't wait to find that out. It's only an eval...it isn't major surgery or anything. And it will give you good piece of mind if it is nothing, or if it is something that needs watching, they can do it now. Also, perhaps read about Sensory Integration (Dysfunction). I don't know how much of the tactile stuff you listed, but that is pretty interesting also. You may find she fits into some of those categories. The Occupational Therapist will be testing for Sensory differences.
Hope this helps.
