I brought my son last time I got tatted. His daddy was with us to handle him. It was fine! We just couldn't let him run free and by the end of it he got antsy/fussy. If he wasn't an easy going baby it might've been too much.
who cares?! as long as you know you a good parent then it don't matter what they think. mine was 7 months when he went into one. people bring 3 month old girls to get their ears pierced there so i don't think so.
