I am beginning to like the name [name]Oliver[/name] more and more but am wondering if it is one of those names that is “cute” as a little boy but not so “cute” for a teenager and and adult? What are your thoughts?
I really like [name]Oliver[/name]. I think it would work for anyone.
I agree. I actually think of [name]Oliver[/name] working better for a teenager and adult, since I don’t know any little Olivers. It just seems like such a smart grown-up name, but I can also see it working for a little kid very well. 
I can picture anything from an adorable little boy all the way to a lovable older grandpa, so I think you’re fine!
I hear [name]Oliver[/name] and immediately think [name]Oliver[/name] Twist, so I do imagine a mischievous little boy. However, [name]Oliver[/name] is a nice name and I can see it on a man of any age.
I know Olivers of all ages, so for me it works well on teenagers and adults as well.
I actually think [name]Oliver[/name] works best on a teenager or older. I think [name]Ollie[/name] is a great nickname for a kid, and [name]Oliver[/name] is still spunky, but works for a grown man. 
Cute for all ages. Go for it!
I think it ages very well. I love it!
[name]Oliver[/name] is growing on me lately too, the only [name]Oliver[/name] that I’ve known was a guy in highschool so I can picture it on a teenager, so I think it can fit all ages.
I love the name [name]Oliver[/name] but I’m biased as one of my twins is an [name]Oliver[/name]. It was my grandfather’s given name as well (although he always went by [name]Bob[/name]) so I can picture it on a man of any age.
I also love the name [name]Oliver[/name].
Have known men, teens and children called [name]Oliver[/name] and it worked. The kids and teens tended to get [name]Ollie[/name].
