Jenna Bush Hager from 'Today' Shared Family Photo from Her 1st Thanksgiving as a Mom of 3

Jenna Hager Bush pose's with her family of five for their first Thanksgiving together since welcoming their son, Henry "Hal" Hager, in the summer.

Jenna Bush Hager has a lot to be thankful for this year. On Thanksgiving, she shared a picture of all four reason's she is "gratefull." Posing with her family; in a caption she says:

"How grateful I am!!!!"

Jenna and her husband, Henry Chase Hager are the proud parents to four-year-old Poppy Louise, six-year-old Margaret "Mila" Laura, and, four-month old, Henry "Hal" Harlod.

The family of five posed in front of a fireplace for their first Thanksgiving together, since welcoming their son "Hal" in August.

Speaking to PEOPLE, about how she juggles her career as a host on "Today," and looking after her three children, she admits that she sometimes misses a lot of moments with them, but ultimately she says:

"I try to focus on what I can do and what I do bring because I think if we beat ourselves up for everything we miss, then we're not as happy of a parent as we can be."

Opening up about another important moment in her life; just a day after her Thanksgiving post, she shared a special tribute in honor of the one year anniversary of her grandfather, Geroge H.W Bush's passing, she wrote:

"One year yesterday, we lost our Gamps. He is gone but he left behind a family that loves each other— we talked yesterday about how much we love him and each other."

"He showed us that serving with humility is the best way to serve and that living with kindness and generosity of spirit is the best way to live."

Jenna ends her tribute expressing how much she misses her "Gampy" and says, her daughter Mila was a source of comfort, reassuring her that he was in heaven celebrating with "Ganny."

Former first Lady, Barbara Bush or "Ganny," as Jenna affectionately referred to her as, left a special memento for her grandchildren she would never meet.

Barbara knitted Christmas stockings for each of them. Thinking she would never get one because there are so many grandchildren in the family, Jenna was pleasantly surprised when she found out that "Hal" was knitted his own pair of stockings for his first Christmas.
