Hey I posted here not long ago some of you may remember but this is an update about the situation.
Spoke to our local bus company stagecoach and they have told me that as my ds is getting a special needs Buggy in a few weeks that he will be entitled to a buggy bus pass which gives him the same right as a wheelchair user on their busses.
This isn't widely known as it's a new pass they have made and only 2 people in Scotland have these passes so I wanted to let anyone else who may be in our situation know its available.
