I find these kinds of comments so annoying! I don’t make comments on subjects, I know nothing about!
DD1 has severe epilepsy. She can suffer a type of seizure called drop attack, whereby she falls down unconscious and may suffer an injury, including concussion, broken teeth or broken bones, at any time. She could break her neck. In fact, if she has any seizure standing up, she can fall down unconscious. Not to mention the dangers of stairs, train platforms, pavements on busy roads, water or sources of heat. We can suffer injuries too, if she knocks us over. Going out with her is extremely stressful, after all the experiences of 999 calls and long waits in A & E! Care workers find it so stressful, they insist on 2:1 staffing to take her out.
Sometimes, when we are going somewhere important like a hospital appointment or a flight, or we do not feel like the stress of another trip to A & E, we take her in a wheelchair. I know other parents with children with severe epilepsy, who do the same thing. Our children can walk perfectly well; but not reliably - they could fall and break a bone within 2 minutes!
DD1 looks normal and able bodied. Nobody should go round making judgments about what other people can and can’t do, unless they know them.
