Can’t decide!

I have a tattoo of my first child’s name and birthday on my forearm I’m due in July and sometime after I plan on getting his baby’s name and birthday under the first tattoo. I don’t plan on having anymore kids but would it make sense to get a bigger tattoo like the ones with the momma elephant and her babies behind her? Or just keep the names and the dates and leave it at that? Sorry if that sounds complicated I tried to explain it the best I could. I want to have the baby’s name under the first tattoo but I also wanna do like a mother and her babies tattoo, is it too much? What do you think?
