Ms. Robbie from 'Welcome to Sweetie Pie's' shares photo of grandson on his 7th birthday

The singer, reality star and entrepreneur took to social media recently to share birthday wishes for one of her grandsons, but made sure to include his cousin in the image too.

Robbie Montgomery, who is known to fans as Ms. Robbie, of the Oprah's Own Network Show Sweetie Pies celebrated the 7th birthday of her miracle grandson, Timmy, who the family fondly refers to as TJ.

The reality star took to Instagram to share a lovely photo of herself holding birthday boy TJ and her other grandson, AJ, smiling delightedly as she did so for the camera.

"Happy 7th birthday Tj. Still celebrating his birthday w/ Aj and granny.6/22 #thebig7," she captioned the image she posted on June 22.

Montgomery wore a bright red button up coat and a matching red and white Gucci cap in the image. She accessorized with a red armband, and a pair of gold hoop earrings.

While AJ wasn't prepared to smile for the camera along with his brother and grandmother, TJ grinned massively in his blue t-shirt with yellow sleeves and blue trousers. He also had a pair of swimming goggles atop his head.

In the foreground, there were two Batman cups on the table in front of the three family members, with a cartoon cityscape on the wall behind them.

TJ is somewhat of a miracle child, as he was born when his mother was just 27 weeks pregnant. Early on in Jenae Wallick's third trimester, she was diagnosed with preeclampsia.

Despite an easy pregnancy up until then, she had to be rushed to an emergency delivery via Cesarean section.

As a result of his early birth, TJ ended up spending the next 5 months in the NICU, receiving round-the-clock care from medical staff.

It was a week before Wallick was able to hold her son for the first time, and her husband, Tim Norman, was scared to touch him because he was so fragile.

In an incubator in the NICU, TJ gained weight as he should, and eventually started breathing on his own. Just as they were ready to discharge him, he developed an infection, and ended up back on a ventilator and medication for his heart.

Luckily, he pulled through, and despite the setback, was able to be discharged at 5 months old. Today, he is still the light of his grandmother's eye.
