E.C.
My daughter used to develop hard knots at the injection site, together with a fever which she would sleep off for HOURS. All of this was deemed normal and I didn't really give it a second thought. Then not long after a HEP B vaccination, she seem to suddenly stop responding to anyone calling her. She also wouldn't maintain eye contact. That was somewhere between her 6th and 9th month, although I want to say closer to the 6th.
At that point, I stopped ALL vaccinations. I started noting that my daughter began to lag slightly on reaching her physical and verbal milestones. Not terribly far, but noticeably. The pediatrician said we would monitor my daughter's progress but I knew that by time something definitive developed, it could be too late.
I began to read on therapies which lessened the impact of the ones she'd had, which is how I found homeopathy. I will never forget administering a certain medicine on my daughter which fit her symptom picture and getting almost immediate results. Her father was skeptical but I noticed a slight change right away. And within the same week, my daughter's caregiver told me that my daughter had said some amazing sentences, which she had not done before (and was late in doing).
If I were you, I would just take note right now. We know our babies so it is ludicrous for people to suggest that huge increases in autism is because of better screening. The moment you feel something is off, ACT.
