I think
Rosie is adorable!! And when she is hear you will gradually call her by a nickname even if you dont realise it, my family has odd nicknames:
My cousin
Isabella Grace is "Belly"
My cousin
Mikaela is "Moo Moo"
My cousin
Eliza is "Roundy"
I am either "Gecka, Boo Boo, or skin and bones"
My brother
Christian is "Chitchin which was just shortend to
Chin"
My boyfriend is "Pee"
Mine came mostly from
Eliza cause she couldnt say
Becka it was Gecka then Boo boo, and my grandmother calls me skin and bones.
Isabella's came from calling her
Bella and since she loves food it just developed.
Christians was because of
Eliza not being able to say his name so it came out like ChiChin or Chitchin.
Isabella cant say
Pierre so she says Pee instead!
Eliza's came because my grandfather said she was more Round than
Eliza lol!! (She is now 11!)
