I was told shortly before dd was 2 that I could have applied for a blue badge because she was using O2 cylinders. She's now 2.4 and uses a ventilator when asleep or tired/ cranky as well as a saturation monitor and on the occasion she isn't well will have an o2 cylinder in the mix as well . Is she still eligible for one? She has joint hypomobility and suspected Spd she still uses a pushchair continuously because she gets too tired walking with her resp condition but has no real mobility issues.
