I used to play with the dolls in the presence of the Prophet, and my girl friends also used to play with me. When Allah's Apostle used to enter (my dwelling place) they used to hide themselves, but the Prophet would call them to join and play with me.(The playing with the dolls and similar images is forbidden, but it was allowed for 'Aisha at that time, as she was a little girl, not yet reached the age of puberty.)(Fateh-al-Bari page 143, Vol.13)
Bukhari Volume 7, Book 62, Number 88:

Bukhari Volume 7, Book 62, Number 118: aisha defines herself as a litle girl
Narrated 'Ursa: Aisha said, "While the Ethiopians were playing with their small spears, Allah's Apostle screened me behind him and I watched (that display) and kept on watching till I left on my own." So you may estimate of what age a little girl may listen to amusement.
Bukhari Volume 7, Book 62, Number 163:
Narrated 'Aisha: The Prophet was screening me with his Rida' (garment covering the upper part of the body) while I was looking at the Ethiopians who were playing in the courtyard of the mosque. (I continued watching) till I was satisfied. So you may deduce from this event how a little girl (who has not reached the age of puberty) who is eager to enjoy amusement should be treated in this respect.
