What are the symptoms of hyperthyroidism in a preschooler?

I have been searching for answers for my 2.5 yr olds sleeping problems since he was about 4 wks old. For the first 7 months, he was waking every 45 minutes around the clock and was unsoothable with just nursing. I had to rock him, bounce him, nurse him, etc. over and over again until he fell back to sleep. We only had one doctor who considered it “abnormal” and that doc did an upper GI for reflux. They just said that he would grow out of it. Well, now hes 2.5 yrs old and still stirs at night every hour or so. I know this, because Ive watched him sleep. He is difficult to put to sleep (it takes hours at night, sometimes) and will sleep restlessly all night long. If we cosleep, he bites me, kicks me, pulls my hair, yells and cries in his sleepall night. This just doesnt seem normal to me.

What have we tried? Homeopathy

Allergy panels (he doesnt eat dairy, eggs, peanuts, or soyno other allergies)

Cry-it-out (tried this for monthsit only taught him to not wake me when he woke up, I stopped this eventually, bc it didnt work)

Reflux meds

A number of other things that I cant remember off-hand. Trust me, though, that I have tried everything obvious. So, my mind wandered to thyroid dysfunction. He is a very hyperactive childnot on meds, of courseand we have some behavior problems with him, as well. His nighttime restlessness struck me as a potential symptom. Are there any other things that I should look for? Anyone ELSE who has experience with a CHILD this small with hyperthyroidism?

I dont think so, based off of what you just described. But, first let me say I am not a Doctor in the least and dont pretend to be. However, I found the question interesting cause my infant son when he was about 2 months old was thought to have congenital hyperthyroidism. As you have probably already done, I read constantly about the disorder. Here is why I dont think so based on what you have said thus far.

1. Usually with Congenital Hyperthyroidism a child will sleep excessively.

2. Other things to watch for is an enlarge tongue.

3. Low body temperature.

4. Infrequent bowels.

5. Poor muscle tone or lethargic

6. Infrequent nursing or eating.

7. Large anterior fontanel and presistant posterior fontanel.

Of course all these can be completely unrelated, so be careful playing the symptom game. One way to be sure is to have your son test for TSH. However, most infants are tested with in the first 2 to 3 days after birth and your physician should have record of this.
