DH and I both have tattoos. He has a longhorn with a texas flag on his arm and a cross on the inside of his other arm he go when his grandfather passed. His grandfather was a WWII veteran and was a POW, so he hopes to add some meaningful symbols to it.
I have 6, they all have meaning.
1 - Outline of Texas with a heart on DFW behind my ear, because Texas is and will always be my home.
2 - Yellow rose on my right hip. As in, the yellow rose of Texas.
3 - Cursive L on my left hip, L is my first initial
4 - "All was well." on my left wrist, it is the last sentence from the last Harry Potter book.
5 - "Love you, Mema" on my left foot. My grandmother has dementia and Alzheimers and I miss her everyday. I took a card she wrote me on one of my birthdays and they copied "Love you, Mema" in her own handwriting. Now even though she doesn't remember me, she tells me she loves me every time I look down.
6 - I have Ya'aburnee written on my right foot inner arch for my DH. It is an Arabic phrase that literally translates into "you bury me", meaning you hope to go before your lover as the mere thought of going on without them is unbearable.
Since all of mine have meaning, I do not see a problem. If my children want to get tattoos when they are adults, I will simply encourage them to select them with meaning.
