Sharna Burgess shares sweet pictures of son Zane 'enjoying swing'

Sharna Burgess is monumentalizing a new achievement for her little son.

The professional dancer shared a video on Sunday of her and her partner Brian Austin Green's almost 4-month-old baby Zane having fun on the playground.

"We just had our first time on a swing and I can't handle the cuteness ….," the proud mom wrote in the Instagram caption. "The eyebrows were working overtime."

The cute movie clip featured a collection of images and a clip of Zane delightfully swinging and grinning at the camera, set to a piano cover of Coldplay's =Clocks.

Zane turned 3 months old last month. Burgess also celebrated it by sharing an adorable video and photo montage.

The dancer captioned the beautiful video: "3 months of you, 3 months of watching you grow, of being in awe of you and of experiencing a love like I've never known."

The picture also featured Journey River, 6, Bodhi Ransom, 8 and Noah Shannon, 10 — who Green shares with ex Megan Fox — in the pool, having fun with their baby brother.
