It's tough but it's Christmas so it's hard not to get people you love something especially since they are kids. Maybe you could do something totally simple for your sisters like frame a picture of the three of you. That way you're not spending a bunch but you got them a little something to open and if they don't get you anything because they are sticking to the secret santas, you won't feel bad. But that's the hard part when you get one person a gift you have to get all of them
