my two kids (7 and 4) have grown up seeing my scars. I've olny ever gone out my way to cover them up if i have had fresh marks (and to keep out of sight of my OH too!). They have never really asked what happened, only 'what is that', or comments like 'mummy, your arms are soo bumpy' infact, my 4yr old seems convinced my arm is covered in a jumper! I think if and when the questions come, I'll try and put it like -"i was sick, and you know like your chicken pox scars, well these scars are from the illness i had. But i feel much better now" i don't know now seeing that written down, they will probably freak out about catching something. But for me, the only reason i have scars is because of the depression, which is an illness i guess. Maybe i do need to think about this a bit more!
