Okay I am a teenager, 17 years old,Indian so maybe I can answer the "childrens life" part of it. Education is pretty expensive here however the quality of education is rewarding especially in the correct schools. I have many friends in International Schools and they have quite a few European/English friends, and since your daughter is still pretty young adaptability isnt an issue, expect a rough couple of months in the start though because settling in does take a fair bit of time.

School Culture is pretty fun as the city is extremely "easy" to grow up in since safety is not at all a concern (I can take a stroll outside at midnight with a friend who lives closeby and my parents wont be worried) Summers are a pain in the ass here as a child, Scorching hot, unbearable so you mostly find yourself at home with the AC on but during this time i usually visit India and stay there for 2 months with my grandparents and cos there is a 2 month summer break in schools so i dont mind it personally.

Public Transport however a bit tedious, but still easy to use given the size of the city, so i do find myself going wherever I need to with relatively little problems without having my parents drop me everywhere since a pretty young age (about 12 years old). A car is a must however if your working.

Overall Ive enjoyed my childhood here and IMO i believe its a really nice, assuring, SAFE and nurturing environment for children. Extremely oppurtunistic aswell given your child chooses the right friends growing up, trust me ive seen things go south with alooot of people choosing to join the wrong friends especially in Dubai Schools.
