(・∀・)桜ちゃんは赤ちゃんの時に、
抱っこのトレーニングをしてもらえないまま我が家にきました。

毎日遊びながら慣れてくれたらいいな。
今はここまででも、充分成長しました。

For a rabbit to be comfortable with being picked up, it must learn through positive experiences that being lifted isn't something that causes harm. This should start when they are just as few weeks old as part of socialisation. The person caring for the young litter should get them used to being touched and picked up so they grow up thinking that it is normal and nothing to be worried about.

Unfortunately many baby rabbits miss out on this socialisation before they go to their new home, or they may have bad experiences later on that make them fear being picked up.
