Need advice! Want to get a thank you gift for friend ...

Ryan • mommy to niko

I have a friend who has 2 children. She has asked me to come over because she has a bunch of stuff that is in great condition for mine... i know they dont have the means for much and this is very generous of them but i want to get the couple something to thank them for essentially saving me money on some baby items...

What do you think i should do?
