i can totall empathize with you!! my son was born with low tone, torticollis and plagiocephaly!! he has been in p/t, o/t, s/t and sees a traditional osteopath. he is almost 4 years old and we are still dealing with it. he had 2 helmets from DOC band when he was younger too.
we are still in s/t and see our osteopath at least once a month - usually every 2 weeks. i also do a lot of sensory therapy at home which helps. he has had eating issues due to textural sensitivities, speech delays and other oral motor problems.
hang in there - it is great that you are doing early intervention!! it is best to deal with these things early as they are cumulative!!! as a former teacher i know the benefits to getting intervention early!! feel free to email me if you have any questions. i will try to find my resources for online oral motor stores where i got a lot of things to help!!
