MIL baby shower

OK so my mother-in-law wanted to do thank you favors for the baby shower even though I already have party favors I told her sure if she wants to but don't overdo it so she doesn't have to worry about the hassle. Then she basically sent me a picture of the finished product and the thank you quote part of it was something she found online and used. I found it online the saying itself and I will post a picture for you to see. So my issue is, not to sound paranoid, but I feel like she is taking a silent jab at me you're making me look below standard or bad in someway. You see the thing is she constantly suffers from empty nest syndrome and he hates any of her sons growing up. She's always been kind towards me but there is a silent resentment in a way for taking her youngest son away from her etc even though he is in his mid-20s LOL. she's the type that gets offended if she is not involved in things in his life and is the type to sit there and tell him to go fill all of his dreams before he settles down, while right in front of me lol etc. she likes to send those type of silent messages. Either way when I read it yes I can understand it has a cuteness about it but it basically says I'm not providing anything for my child but thanks to you he actually has some stuff now. I don't know it may just be in my head but I know how she is and I feel like it looks bad on me in some small way. So what do you think? I wish I had saved the picture she sent me but I didn't but this picture on here is the basis of the saying she used.
