Thanks for all these! I’ve finally got back to my friend and her favourite list has been extended!
For boys: [name]James[/name] & [name]Daniel[/name] (the current top 2), [name]Noah[/name], [name]Jude[/name], [name]Albert[/name], [name]Eli[/name] & [name]Oliver[/name]
For girls: [name]Sophia[/name] & [name]Poppy[/name] (other top 2), [name]Lottie[/name], [name]Rose[/name], [name]Eve[/name], [name]Lily[/name], [name]Evelyn[/name], [name]Matilda[/name] & [name]Georgie[/name]
I see you are from the UK so I can say that these names are pretty popular/common, does that bother your friend?
[name]James[/name] and [name]Daniel[/name] really isn’t for me but I adore [name]Noah[/name] & [name]Jude[/name] (popular but not overdone)!
[name]Matilda[/name] & [name]Sophia[/name] / [name]Matilda[/name] & [name]Evelyn[/name] would get my vote for girl’s. I thin [name]Poppy[/name] sounds quite nicknamey alongside [name]Sophia[/name] and I don’t think they work well for twins. [name]Sophia[/name] & [name]Lily[/name] would be nice.
I have [name]Milly[/name] sat next to me now. I’ve got to convince her to become a berry 
She knows they’re popular but doesn’t mind so much because she doesn’t know any other kids with those names (yet!). Most of the kids at her son’s nursery are either called [name]Jack[/name] and [name]Emily[/name] or [name]Jordan[/name] and [name]Mackenzie[/name] so she’s not that bothered.
[name]Noah[/name], [name]Poppy[/name] and [name]Matilda[/name] didn’t turn out very well with her DH but she’s determined to get her way! The current idea is:
B/G: [name]James[/name] [name]Daniel[/name] & [name]Charlotte[/name] [name]Sophia[/name]
B/B: [name]James[/name] [name]Noah[/name] & [name]Daniel[/name] [name]Jude[/name]
G/G: [name]Sophia[/name] [name]Evelyn[/name] & [name]Charlotte[/name] [name]Poppy[/name]
DH’s suggestion was: Twin 1 and Twin 2. Helpful Anyway, she says to thank you guys for all the suggestions. She hadn’t considered [name]Charlotte[/name] or [name]Evelyn[/name] before. And she’s got another 5 months to do some fine-tuning!
[name]Sophia[/name] [name]Rose[/name] & [name]Daniel[/name] [name]Jude[/name] are adorable
I think [name]Sophie[/name] & [name]Piper[/name] would be precious!!
