I have a friend due with a little lady in Dec, and trying to brainstorm with her about [name_u]Piper[/name_u] and [name_u]Harper[/name_u] alternatives (we know one of each).
Any suggestions?
[name_u]Tatum[/name_u]
[name_f]Scarlett[/name_f] (nn [name_u]Scout[/name_u])
[name_u]Avery[/name_u]
[name_u]Bailey[/name_u]

[name_u]Quinn[/name_u]
[name_f]Imogen[/name_f]
[name_f]Journey[/name_f]
[name_u]Marley[/name_u]
If she’s specifically looking for names that end in “-er”:
[name_f]Summer[/name_f]
[name_f]Esther[/name_f]
[name_u]Skylar[/name_u] (or [name_u]Schuyler[/name_u], or [name_u]Skyler[/name_u])

[name_u]Sawyer[/name_u]
If not, some random other suggestions:

I love [name_u]Fifer[/name_u]! You could go with the [name_m]German[/name_m] spelling, [name_m]Pfeiffer[/name_m], but I prefer the straightforward, [name_u]Fifer[/name_u].
[name_f]Poppy[/name_f]
[name_u]Juniper[/name_u]
[name_f]Hester[/name_f]
[name_f]Lavender[/name_f]
[name_f]Summer[/name_f]

I know two little sisters named [name_u]Parker[/name_u] and [name_u]Finley[/name_u]… Super cute! 
[name_u]Quinn[/name_u], [name_u]Wren[/name_u], [name_f]Isla[/name_f], [name_f]Lark[/name_f] all beautiful names.
I like the suggestions of [name_u]Juniper[/name_u] and [name_u]Fifer[/name_u].
I like [name_m]Prosper[/name_m] for a girl. What about [name_f]Aster[/name_f], [name_f]Favor[/name_f], [name_u]Vesper[/name_u], or Hesper??
[name_u]Vesper[/name_u], [name_f]Esther[/name_f], [name_f]Clover[/name_f], [name_u]Winter[/name_u], [name_f]Hannah[/name_f], [name_u]Halle[/name_u], [name_u]Demeter[/name_u], [name_f]Phoebe[/name_f], [name_f]Holly[/name_f], [name_f]Heather[/name_f], [name_u]Juniper[/name_u].
[name_u]Hadley[/name_u] is my first thought.
