As I wrote above, boarding last often mean no storage space in your isle to put you and your children's bags.
An adult with 1 carry-on can easily compensate for the lack of storage and either find another available storage compartment in another isle or ask an attendant and as that is the only thing you have to keep track of the likelihood of forgetting it is low (although even then, not unheard of).
For a parent with 2 children, having your 2 or 3 bags being stored in multiple locations as well as maintaining order of your kids increases the likelihood of something being left behind exponentially.
