Was it reasonable to buy herself one before ensuring the children all had equal access to a horse for hunting?

I feel passionate about this one. She sold her tiara to buy the horse; it was her particular property. Mothers do not always have to take care of the children first.

As to the horse, it's Ginty's birthday present; it is customary in my family that large birthday presents do not have to be shared. On the other hand, the other children could now reasonably expect horses for their birthdays...
