It may still be quite a few days away, but it's wise to prepare for it, starting today! That is if you want to make extra 12,000g during it!
As you may know, certain items will be VERY high in demand during the Children's Week, even if they are super easy to obtain. But let's face it, people are lazy! And that is what makes us rich
Also certain items are "harder" to acquire now with the portals gone, such as Dalaran donuts!
These are the items that will have their prices rise to the roof during the first day of Children's Week, and in many realms even before that! Last Children's Week happened during WOTLK and people were way more poor back then, so the prices will be even higher now, but are still only estimates!
Popular items and their estimated AH prices during the first days of the event (Yes people buy vendor sold items from AH!):

Warning: The prices will keep dropping as the event continues, so start listing your items the day before the event starts! The prices are only estimates and are based on what people pay for easy to obtain items on my realm. People will undercut you a lot on some realms, and on other realms the same items may go for 200% higher prices!
Note: You should not farm these yet. Instead, check your AH every day and see if these items are sold for ridiculously low prices and buy them! But do not buy vendor sold items. You will be the one selling them in AH when the time comes!
