Nice gift for my client?

Sooo, I have a client of mine who is the absolute most wonderful woman I have met. I started working with her in January and have to stop in a few weeks due to going on maternity leave.

Now, let me give a backstory on how much she’s done for me.

When she found out I was pregnant, she gave me baby clothes that her son no longer fits into, a swing, a mamaroo rocker, a door bouncer, a UppaBaby Mesa car seat, a really expensive diaper bag, a breast pump, this boppy thing that helps the baby learn to sit on their own, a bath tub, and so much more.

She’s helped us tremendously! Her husband and her both have money so a materialistic gift probably wouldn’t be ideal.

I need help with a thoughtful gift...
