I’m pregnant with our second child, and while we don’t know the sex yet, our top boy’s name is [name_m]Isaac[/name_m]. But there are already two Isaacs in my son’s preschool class. Would naming a baby [name_m]Isaac[/name_m] seem somehow ridiculous, or confusing to our son? That’s really my only hesitation about the name. Your input is appreciated!
If he already knows two Isaacs, I don’t think it would be that big of a deal to him. [name_m]Isaac[/name_m] is a popular name. He’s bound to meet even more Isaacs, anyway.
If you love [name_m]Isaac[/name_m] that much, nothing wrong with using it of course. Good name, great meaning, cute nicknames ([name_m]Ike[/name_m] & [name_u]Izzy[/name_u]). I think it was #31 last year for boy names in the U.S. For me, I’d always be looking for a much less popular name but what’s more important is that you really love the name you give your child. I’d say keep an open mind to other names throughout the pregnancy but if nothing ever tops [name_m]Isaac[/name_m] then there you go.
No. Ridiculous or confusing would not be the words I would use at all. Your first first son will be fine (maybe rethink if he is already friends with an isaac). However, I’m not sure how popular isaac is right now, but coming from someone with a VERY popular name, but if it is in within the top 40 names, I would encourage you to think beyond. I always hated being “[name_f]Jessica[/name_f] K.” because there were 5 other Jessicas in my grade.
You need to decide how important popularity (or lack thereof) is to you. For me personally, a name already taken by two children we see regularly would be automatically “out”–not because it’s ridiculous or confusing, but because I prefer names that are less common than that.
On the other hand, naming trends change a lot quicker today than they did just a few decades ago. A name shared by 3 preschoolers right now might not even make the roster in 5 years, and something else that sounds “new and different” might surprise you with how trendy it becomes. If you really love [name_m]Issac[/name_m], it might still be “the name”, even if it is more popular than you’d like. HTH 
Thanks for your input! We have lots of time to consider it (and who knows, we might have a girl)…but I’ll keep your thoughts in mind
