You're wonderful. I'm a single mom and it's tough, I wish you all the luck. Some books I've found- based in the age of her kids.

Is this going to be anonymous? If not, ask to borrow her car one day. Say yours is in the shop. Fill it up with gas, wash it, change the oil, whatever you can afford to do.

If she has things on layaway, go pay them off.

These are mostly all monetary things, I know, but it sounds like she may be struggling a bit on that end.

Nominate her or put her name in for draws, raffles, anything. I know the radio stations here sometimes have a week where you can nominate someone awesome for whatever. This could be a good way to do things anonymously.

If you are close to the friend, you can do little things through her. Get her a gift certificate for something, have the friend say she won it and won't use it.

Good luck!!
