You have an expander you can take out yourself?! Wow, I'm jealous
Mine was fixed, and I was lumbered with it for nearly 8 months!
Seriously though, it must be very tempting to keep taking it out. And if you speak on the phone a lot and take out the expander every time, then that must add up to a lot of time when you're not wearing it. I don't know about it getting loose, but I would imagine it can't do its job properly if it's not in your mouth long enough.
My speech always sounded a bit "different" when I had my expander, but the more you practise he better it gets. I still had to read my son his bedtime story of an evening and I'm sure that helped
. The rainbow passage, often quoted on this board, is also a good way of practising all the sounds:
"When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow. The rainbow is a division of white light into many beautiful colors. These take the shape of a long round arch, with its path high above , and its two ends apparently beyond the horizon. There is, according to legend, a boiling pot of gold at one end. People look, but no one ever finds it. When a man looks for something beyond his reach, his friends say he is looking for the pot of gold at the end of the rainbow.
Throughout the centuries men have explained the rainbow in various ways. Some have accepted it as a miracle without physical explanation. To the Hebrews it was a token that there would be no more universal floods. The Greeks used to imagine that it was a sign from the gods to foretell war or heavy rain. The Norsemen considered the rainbow as a bridge over which the gods passed from earth to their home in the sky. Other men have tried to explain the phenomenon physically. Aristotle thought that the rainbow was caused by reflections of the sun's rays by the rain. Since then physicists have found that it is not reflection, but refraction by the raindrops which causes the rainbow. Many complicated ideas about the rainbow have been formed. The difference in the rainbow depends considerably upon the size of the water drops, and the width of the colored band increases as the size, of the drops increases. The actual primary rainbow observed is said to be the effect of superpositioning of a number of bows. If the red of the second bow falls upon the green of the first, the result is to give a bow with an abnormally wide yellow band, since red and green lights when mixed form yellow. This is a very common type of bow, one showing mainly red and yellow, with little or no green or blue."
