Speech delay and congenital hypothyroidism

My daughter was diagnosed with congenital hypothyroidism at birth and has been on thyroxine since she was 11 days old (we live in London, England.) At the time of her diagnosis we were told that she should experience no real developmental or other difficulties, although at a subsequent appt. we were told that she may have difficulty writing.  She is seen regularly and her levels checked and medication adjusted accordingly.  However, we get very little information, even when we press for it.

She is now 28 months.   She seems to be bright and able - she can identify colours, shapes, loves books and can follow instructions easily.  However, she has only about 20 words in her vocabulary: she has never said daddy or used her own name, although she does say mummy and cat!

We have a referal to a speech therapist which will come through in about 8 more weeks.  However, we would like to know if speech delay is linked to congenital hypothroidism and what other developmental problems she may experience.

I basically agree with the guidance you have received. The hypothyroidism per se, particularly since it was diagnosed early and is being treated, would not lead one to think that your daughter should be experiencing problems in the development of speech or language. You are on the right track by seeking the S&L evaluation.
