As adults, with 4 of us kids, our spouses, my half brother and his wife that my Mom took under her wing (our father and my step-mom/half bro's mom were deceased), plus the adult grandchildren...my Mom had many to buy for (plus all the little ones). She was famous for handmade items she worked on throughout the year, but the store bought gifts were well known too!
She started this trend of buying us safety items which many of us still use and appreciate. Fantastic first aid kits from the Red Cross (many of us hunt/fish/snowmobile,and I do home childcare so they are great to have and use). Carbon Monoxide detectors. Fire extinguishers. NOAA weather radios. LED flashlight sets for all over the house.
Then she made us things like scarves, hats, mittens, ornaments...all personalized and special.
Now that she is gone (she passed away 5 years ago), we all remember her fondly and how she wanted us to be safe. All of the items are still relevant and useful all these years later! I know I will do the same when my own daughter moves out on her own!
My in laws spend less than $100 on each of us. We usually get a shirt, sweater or PJs , maybe a book or CD or something they know we wanted, then a family item like game, video game, movies, or movie tickets, etc. They spend a little more on our daughter, even tho she is 18 this year. She gets a few more gifts, which is what we would prefer if they are doing a budget for each family "unit".
Good luck and Happy Holidays!
