Levothroid pills during pregnacy.. Child Development issues?

I was diagnosed with Hyperthroidism - 9 yrs ago (age 20) after the birth of my 1st child, I had the radiation treatment and my condition turned into hypothroidism. Currently I am on 175mcg daily of Levothroid. My levels were watched closely and adjusted accordingly when I became pregnant with my second child. He is now 6 yrs old, he is border line ADHD and having issues learning and focusing in school (along with behavior problems). Also has migraines, night terrors, and sleep walking. I wanted to know if anyone else had the same issues as I do with child development. It has to relate to the Levothroid pills or maybe the radiation treatment....??? My 1st child is excelling in school and has highest honors. I don't want anyone to tell me they are different children, I feel my medicine has something to do with the development of my 2nd child. Please let me know your thoughts, is anyone else in the same boat as I am??????

I did not get pregnant until 3 yrs after my radiation treatment and was stable on my dose of medication. During pregancy it was monitored and was increased slowly as required.
The pregnancy with my son was more difficult than with my 1st. (the second is not always easier) He was born (induced) 3 wks early due to my low platelet count, I was not allowed any pain medication. After 10 hours he was born - but no issues during labor. I have been researching this medication, I found this last night but have see other indications of a possible connection: "In fact, the babies of mothers who were hypothyroid in the first part of pregnancy, then adequately treated, exhibited slower motor development than the babies of normal mothers. However, during the later part of pregnancy, hypothyroidism in the mother can also have adverse effects on the baby. These children are more likely to have intellectual impairment.

I don't think it was your thyroid pills. I was on pretty hefty doses with all three of my kids. With the last one, I was up to 300 mcg a day. (My kids are all great students with normal behavior and sleep patterns.) The greater danger (when you're talking about hypothyroidism) is to leave it untreated and risk the baby developing a problem due to your out of whack thyroid. Thyroid replacement pills are in a safe for pregnancy class.

Was the second baby born early? Sometimes premies will have developmental problems....was there any fetal distress during your labor or delivery? Another cause may be a food allergy or sensitivity. We have friends who had a child with similar problems. He is doing better now that they have found he has an allergy to gluten.

Good luck to you and your little guy....
