Autoimmune?: If you had graves' disease it is autoimmune disorder which are familial and tend to be passes along to the children. Up to 50% may get an autoimmune disease as well.

Unfortunately, yes.: A fetus is dependent on maternal thyroid hormones for the first 12 weeks of pregnancy till it can make its own. Thyroid hormones are important for fetal brain development, which occurs the 3rd -8th week after conceiving & continues throughout pregnancy & beyond. Tell your pediatrician & seek evaluation of your child's growth & development at your state's Early Intervention Program.
