Otis - don't like it
Luca - like it
Gabriel - like it but agree with you re Gabe.
Clara - quite like it but no good if your husband doesn't
Jessica - love it. I have a 7 year old Jessica and know of maybe 4 others under 12. I don't understand how it's always so high on the lists.
Poppy - not keen. It's quite cute though
Sadie - love it.
From your list I'd go with Luca and either Jessica or Sadie.
