Cardi B cannot believe how fast time is flying by.

The rapper, 29, uploaded a carousel of photographs of her infant son Wave Set on Instagram Saturday, where she marveled at how her little one is already 9 months old.

"Happy 9 months Wave 🌊🥺!!" Cardi captioned the series of shots. "My baby growing too fast on me."

In the selection of photos, Wave can first be seen wearing an all-blue ensemble with a chain around his neck in two shots, as the little boy poses with a happy smile in the next.
