I just found out I’m pregnant with baby #5! I have a [name_u]Michael[/name_u], [name_m]Matthew[/name_m], [name_m]Luke[/name_m] and [name_f]Lily[/name_f]- never thought I’d have a 5th haha - would it be weird to not do an m or l name for this baby?? If not I like [name_m]Leo[/name_m] and [name_u]Logan[/name_u] for boy names but no idea for girl names (not finding out gender). Any advice or suggestions? Thanks!
Maybe if you went one letter over in the alphabet—N or K?
Anyway, some girl names:
[name_f]Kate[/name_f]
[name_f]Leah[/name_f]
[name_f]Maya[/name_f]
[name_f]Mia[/name_f]
[name_f]Molly[/name_f]
[name_f]Natalie[/name_f]
[name_f]Nora[/name_f]
I don’t think initials matter too much unless you make a big deal of it. Some ideas that sound nice with your other children’s names:
[name_f]Eve[/name_f]
[name_f]Grace[/name_f]
[name_f]Claire[/name_f]
[name_f]Katherine[/name_f]
[name_f]Charlotte[/name_f]
[name_f]Caroline[/name_f]
[name_u]Meredith[/name_u]
[name_f]Anna[/name_f]
[name_f]Elise[/name_f]
I would choose another letter altogether. I think that three the same eatablishes a definite pattern so you’re not there yet, and I prefer children to have their own initial as they are individuals rather than “sets”. [name_u]Michael[/name_u], [name_m]Matthew[/name_m], [name_m]Luke[/name_m], [name_f]Lily[/name_f] and…
[name_m]Alexander[/name_m]
[name_m]Ethan[/name_m]
[name_m]Oliver[/name_m]
[name_m]Duncan[/name_m]
[name_u]Jameson[/name_u]
[name_f]Charlotte[/name_f]
[name_f]Alice[/name_f]
[name_u]June[/name_u]
[name_f]Adeline[/name_f]
I don’t think you need to be concerned about syncing with a letter you have already. As long as it’s a fabulous name, he/she will feel special to be an original 
All of your kids have pretty classic, solid names, so you’d be fine with almost any classic name you’d choose.
Thank you everyone! You are very helpful!
