hi -
there is no way to permanently change your child’s muscle tone. Neurologically, muscle tone cannot be changed under voluntary control, regardless of exercise and diet. That being said it depends on what your goals are. if your child has low muscle tone that is impacting his/her ability to engage in certain activities – such as sitting at a desk and engage in writing/other desk top activities -- then you can perform activities to increase awareness (short term) of his body/muscles/joint to increase his/her success. Remember that depending on how low tone a person is they can be completely functional (there are varying degrees – from mild to moderate to severe – mild is decreased ability to move against gravity with good speed and accuracy and severe low tone would be not being able to lift your body against gravity).
here is a link to a handout on line that maybe helpful (depending on the age of your child): http://www.rch.org.au/emplibrary/ot/InfoSheet_C.pdf
I'd say that if you feel your child's low tone is impacting his/her ability to engage in daily activities consider asking about a physical therapy or occupational therapy evaluation.
