If you have an egate card can you take your child through with you? She is 3 has a passport but no egate card?
I did this with my grand daughter, had no problems.
Yes thats all and also a valid residency permit. Qucikest way I have found is at T3 Information desk opposite the entrance. Costs AED200 if an individual e-gate card but I understand it may be cheaper if you add to your UAE ID Card.
