The desert sun can be harsh on both you and your children.
Bring an ample supply of sunscreen and a hat for each member of the family. You’ll also want to travel with plenty of water bottles as dehydration will be a concern for much of the journey. Consider snacks that can withstand heat such as dried fruit, granola bars and individually wrapped hummus tortillas. A travel pillow will be indispensable when your child wants to sleep.
There are pros and cons to bringing a stroller. It’s useful to have one while shopping in Makkah and traveling from hotel to mosque. A stroller that reclines to a flat position is also great for sleeping. However, strollers are not allowed in or around the Grand Mosque during Hajj.
Also, keep in mind you can hire a wheelchair to ferry children around Makkah. So it might not be necessary to lug a stroller around for the entire trip.
