Sarah on Instagram: "My kids wanted a debit card rather than just cash (they are 7 and 9) and I was looking at different options but if you are a @NatWest customer you can get a @natwestroostermoney card for free where you can add money and set challenges/chores. I am wondering if my kids no longer believing in Santa means I can get out of elf on the shelf this year? #workingmum #familybudget #teachingkidsaboutmoney #toothfairy #parenting #ukmum"
