Sustainable Kids Jeas

[livingsustainably]

Hi I am a final year design student creating some sustainable jeans for kids and was wondering if anyone would be able to answer some questions in relation to it? I am mainly focusing on children between the ages of 4 and 8.
I have attached some images and questions, Thanks.

What a lovely idea! I would suggest popping this on Survey Monkey or similar as it's hard to answer this way.
I found when my kids were little they outgrew their clothes, now they are 7 and 10 they wear them out. Mainly at the knees.
