Is money received from my mother every month an income? If my mother sends me some money every month, is that considered an income?

I usually fill in a sheet to track my expenses and display my savings for every month. For the past few months, I've been living on my mother's generosity to sustain myself while I'm studying. 
I was categorising this as an income but felt it wasn't right. 

The question is, What do you call the money you receive from a relative every month for a fixed period of time in exchange for basically nothing but your well being, education etc.? 

I intend to share this sheet with students who might be receiving some sort of financial assistance from their relatives. The need for me to come up with a term that rightly describes this transfer of cash is to avoid any sort of confusion while using this sheet.
I will simply repeat what I've said in the comments, just so that there's a concentrated version of the argument.

What you are describing is not 'income' but a kind of 'transfer' payment. Your mother transfers an amount of money from her account to yours.

It is possible to consider it an 'investment' on her part; she would be investing in the increase of your human capital stock; such an approach would imply that she would have a claim on a part of your future income stream.

Since, usually, parents don't enter into contractual agreements with their children concerning their future income possibilities (that I know of) I would argue that from the viewpoint of you both, what you are receiving and what she is delivering is a cash transfer.
