Thyroid Problems?

[dm86]

Hi all.Just wonder if anyone has ever had experience of thyroid problems in children?
I've been diagnosed for 3 years now with Hashimoto's.It runs right down my mums side of the family and all aunts and my sister has it.
Over the past month my 6 year old daughter has not been well.The symptoms started ringing alarm bells.Really really tired,constantly cold,achy arms,pins and needles and a constant sore throat. Would you get her tested or am I being an over frantic mother! It's just like someone's got a Hoover and sucked all the life out of her ð???
Has anyone any experience of this? Thanks!
