Too similar? Rohan & Rosie?

[kristi14]

I think Rohan and Rose/ie sound good together. I do think Rohey (nn) and Rosie (nn) are too similar though and the children would get confused as to who you are calling all the time. I dont think Charlotte is too long, i think its a gorgeous name and if you dont want her name shortened to Charli, then it wont be. I would more call her Lottie, before Charli

i think Rohan and Rose would be ok but if you call ds Rohey and would call Rose Rosie it could get a bit confusing and be to close

thanks everyone!!
Rohan is growing up so less likely to be Rohey and more Ro. (he is almost 8)
There is no theme, my DS2 is Lucas.
We have a thirteen letter surname, so the shorter name the better. Even though we have liked Charlotte forever.
