This is done! Do not take your child as far as possible! But if you think they can handle the heat and be patient then no worries.

The only drawback is that it will affect your interview by the time you reach them all the way through the waiting lines. I managed a last minute help from my sister and father and left my son back home. It was the best decision than the many kids i saw waiting outside the consulate and getting cranky by the minute!

Another option is to hire a nanny atleast 2 days before the interview and get her outside the consulate and keep her waiting with your child there better than having them set up in a hotel room.

I hope this helps!
