<human>: Give me a shortened version of the text

My mom is 48 going on 49. We rarely ask her for anything so this is out of love. She has almost nothing in her bank account and makes about $12/ hour (she does have a 401k). She owns a mobile home that's about 15 years old (lived there for the past 8 years). Not in great condition but it is live-able space. She isn't very good at saving for herself.

Me and my 2 sisters are interested in opening an account or trust fund or something that only the 3 of us will know about and can only deposit until maybe Xmas 2016 or so. I tried googling the best account/solutions but haven't ran into anything yet. Our goal is to present our mom with the money. Since it's three of us and we all have a very tight budget each one of us will deposit about $20 bi weekly. I approximate we will have about $2k to present to her. Is a CD, savings, trust fund, etc. a good place to hold the money?

What advice would you give us to help out our mom?
