Plz help me with gift ideas for her!

She's my girlfriend...we have a kid together and live together. Her style in clothing is hard to predict, I usually get her jewelry but Id rather get something other than jewelry this time. She already makes a lot of pictures and frames them on her own of our family,.etc so that's kinda out the window.

She is 31.

My budget is around $100. So I really couldn't get jewelry anyways. I already got her a new kitchen set but feel likemk should get something else too can anyone help me because I'm terrible at this.
