I am pregnant with my 4th child, I have [name]Myles[/name], [name]Leila[/name] and [name]Bronwen[/name]…is [name]Delilah[/name] too similar to [name]Leila[/name]? I also like [name]Sloane[/name]. Opinions and suggestions welcome!
Yes, I think [name]Delilah[/name] is far too similar to [name]Leila[/name], personally. I’m assuming your [name]Bronwen[/name] is a girl, so correct me if I’m wrong! So, you’ve got [name]Myles[/name] with a surname-y name, [name]Leila[/name], with a very girly name, and [name]Bronwen[/name], with a Welsh name that can be unisex ([name]Bronwyn[/name] is the masculine form in [name]Wales[/name]). For another girl, I’d stick with a two-syllable, since that is what you’ve got going for [name]Leila[/name] and [name]Bronwen[/name]. If another boy, perhaps another one-syllable name? I’d recommend something like these for your fourth child…

Stupid question, but [name]Leila[/name] is pronounced [name]Lay[/name]-la, right?
I think lie-la would obviously be too close to [name]Delilah[/name], but not lay-la. Sorry if I’m not much help. 
I’m pronouncing [name]Leila[/name] the same way you are, coutureforsure, but I don’t know how mom is. I still think they are too close, personally…
[name]Leila[/name] is pronounced lay-la. [name]Bronwen[/name] is a girl. So far for a boy we like seth, but we need more ideas for both! Thanks, keep the ideas coming
