My son (who is 4 now and was officially diagnosed with Autism in April of this year) started out like every other child..crawling,walking,jibbering,doing everything on time,he was always a little "high strung" and liked things a certain way,refused most foods and would eat 5 things (mostly dairy,yogurt and cheese) but I just figured he was one of those picky kids...it was at around 18 months, his word formation began changing..he started regressing in his vocabulary,in which resulted in more and more frustration that turned violent (head banging,hitting,kicking), soon he began to show signs of digestive trouble (severe constipation for a week, then would have diarhea for days),began keeping constant ear infections,& he seemed to be getting intolerant of simple things like lights,music,groups of people,and textures like grass and fabrics of clothes. At his 2 year appointment, I was desperate for some answers,some support,some direction of what was going on,but sadly, his doctor (who i gladly kicked to the curb) said he needed time outs and his speech/language issues were "typical childhood stuttering"...after doing hours and hours of research, I knew something else was going on and found a new doctor who recommended us to all of the right people, we saw nutrionists,gasterologist,ear nose and throat docs,pyschologist, and sppech and language therapists. After months and months of testing (and waiting to get in to see these people!) we finally got the confirmation of what I had known for 2 years, he is Autistic. Reguardless of why you may think your child is on the spectrum, let me encourage you to do all you can to get early intervention for whatever the problem may be. Good luck and if you ever neev advice or would like to just talk, feel free to contact me anytime!!
