I told my daughter when she was 6 years old, she'll be 11 next Monday.
Telling her was a good decision, because she is no longer worried or confused by my behaviour.
Normalizing it and encouraging her to ask questions has eradicated any fear or uncertainties she may have had before.
Hopefully being honest with our kids, will mean that they grow up to be part of a stigma free generation. Hopefully our openness will allow them to live stigma free, whether they develop it themselves or meet people who are afflicted. Hopefully our honesty means that future bipolars won't be as lonely as many of us are today.
One can hope
