Congratulations!
I first want to say that [name_u]Landon[/name_u], [name_u]Greyson[/name_u] and [name_u]Corbin[/name_u] are such beautiful names! I’m not sure if this was planned but I absolutely love how each of their names end in the same sound. This made reading your list of names a little easier to tell which ones fit more, in my personal opinion.
I went through a phase where I loved the name [name_u]Rylan[/name_u], I too have a warm spot for the nickname [name_m]Ry[/name_m] and felt it was a name that was unique in it’s own way but with similar alternatives like [name_u]Ryan[/name_u] and [name_m]Ryland[/name_m], has it’s own beat but, is not too far off the path from traditional or more popular names! However, I found it to be too feminine for my personal naming style and haven’t felt the same about it since.
Kieran is such a sweet name and would go lovely with [name_u]Landon[/name_u], [name_u]Greyson[/name_u] and [name_u]Corbin[/name_u]. I also love the sound of [name_u]Kieran[/name_u] [name_u]Jesse[/name_u]. I myself am not the biggest fan of the name [name_u]Jesse[/name_u] either but I feel it works so well with [name_u]Kieran[/name_u].
I am 50/50 on [name_m]Graham[/name_m]. There is a part of me that finds it to be such a sweet simple name that can be adored in any stage of life, and then there is the other part of me that feels compared to your boy’s names it won’t mesh so well. [name_f]Awesome[/name_f] meaning however!
I actually love [name_m]Caden[/name_m], I think it might be my favourite off your list. It’s not a name you hear so often but still simple enough to coexist in the realm of traditional, classic or even trendier names. It goes absolutely perfectly with [name_u]Landon[/name_u], [name_u]Greyson[/name_u] and [name_u]Corbin[/name_u]! I find it to be an incredibly strong sounding name and I love the meaning of little warrior, so sweet!
Nolan is one of my least favourites from your list, I personally just feel that it has been quite overused in the past ten to twenty years, and although it would match with the “en” sound as your boy’s names have, I am not sure it would flow as well all together. I too find it hard when names have words within them like "No"lan, "No"ah, it would make some moments very testing I feel haha. Personally just not my favourite but still a nice traditional name!
Kove/Cove has a beautiful meaning and I love the sound of it, however I am just unsure of how well it would work with your other boy’s and I feel compared to their names, he would have the most unique name out of the bunch, which is completely fine, but maybe just something to think about with this one? I also can see how the association to Covid could sway your decision, which I personally agree with and would avoid for this reason alone.
I am gonna have to say that [name_m]Caden[/name_m] is by far my favourite from your list. I think [name_m]Caden[/name_m] [name_u]Jesse[/name_u] sounds wonderful together, it’s a strong simple name but also is so sweet and loveable! [name_m]Caden[/name_m] goes perfectly with [name_u]Landon[/name_u], [name_u]Greyson[/name_u] and [name_u]Corbin[/name_u] while having it’s own individual sounds as all your boys do! I hope this helped and I wish you and your husband the best of luck on baby #5!
Congratulations again [name_f]Caitlin[/name_f]!
