Don't tell anybody how old you are. I became a nurse only weeks after my 20th birthday. I hit the floor and people would make comments about how I was so young to be a nurse and ask how old I was, and I didn't ever tell anybody until my 21st birthday was approaching, a year after I started working there. They didn't believe me til I pulled my driver's license. Of course now my nickname is "Little one" at work, but they had already learned to respect me as a nurse, so my age doesn't really ever come up except when talking about stuff like old tv shows
. One thing that's helpful is to be assertive and use a low voice--I had the habit of speaking in a high pitched voice due to trying to be nice/polite and also out of nervousness, but people will take you more seriously if you don't do that. But you've got kids and experience as a CNA. You're not green, you're grown,
and you shouldn't feel bad responding to questions about your age with non-answers like "Old enough" "I'm grown" "85" etc. Or play it off like "And how old are youuu?"
