Hi, I am a professional tattooer with2 kids, one 7 and one 8 months. All I can say is don't worry about it.
Granted, I live in a very liberal and accepting city but even so, if people are going to judge you then there is nothing you can do about it and really no point in honoring their judgements by changing yourself to please them. Trust me, it won't please them a bit. This issue is the same as any other kind of discrimination. If we hide, we get treated like we're hiding something. If we act like we have lesser rights than others then that's how we will be treated, etc. So, in respect to your kids - Love them and honor them by showing them that you love and honor yourself. Don't let others treat you OR your children as though you have less of a right to your life and your choices than anyone else has. Take your kids to school, pack them a good lunch, make them do their homework, teach them to share and be kind to others, make sure they get the support and attention that they need. I gaurantee that's what the people who really matter will notice and that's what matters to them. Sure, there will be snotty soccer moms and asshole jock-o dads who look down at you and what-not, but so what? Those are the same snotty cheerleaders and asshole jock-os that we dealt with in high school. They will always be there, but if carry ourselves with pride and dignity, then it's them whose true colors will show through and we will win the moral victory. And if that doesn't help, then we can always just kick their asses after school, right?
