There are a range of management options available but you really need to discuss these face-to-face with a physiotherapist. Children can vary a huge amount following a birth asphyxia and so there is no "recipe" of treatment. A thorough assessment needs to be made in order to identify the most appropriate methods for you to use. If you are not already in touch with a physio. ask for a referral from your G.P. to your local community paediatric physiotherapy department. Hope this is of some help.
