I see what OT says about the gift, he's right, but I look at it as bringing some humor into a tense lifestyle. Humor is an ice breaker, so to speak, all that has happened with your W and D, has been stressful, so making a cute gesture without a "heavy" meaning gift or no gift at all, shows her that you thought of her.
Either way - you could always give it to your D. She liked it...
