My 4 year old asks questions like. After a fall she was saying "I almost cracked my head" and I told her that Allah Mian protected her. Now she was asking did Allah Mian made his own hands? Then the other questions are Who made Allah Mian? How does he look? I cannot give her answer as I would the older one but any suggestions on age specific answers.
So cute and smart Mashallah.
You are her role model , she will accept any wise or foolish answer. It is upto you.
for example to my daughter I told " Allah is like light you do not see it but you see every thing the light reflects from." I do not know if she understood or not but she did not repeat the question. " No Allah does not have hands he just orders the things to happen and they happen, he does not have to use his hands to do anything therefore he does not have hands or feet like we do" To my son I told " To be Allah he had to be creator of everything , if some one created Him then how can He be Alllah and the ultimate creator" Then I told him about Sura a Ikhlas.
