The first few months with a baby go by in a blink — and it seems like yesterday that Chip and Joanna Gaines welcomed their fifth child, Crew Gaines, to the world. Yesterday, it turns out, was June 21st, 2018, and now the adorable toddler is more than six months old.

In a new Instagram post sharing two photos, Joanna Gaines shares just how much baby Crew has grown, writing, "He's proud of his first TWO teeth!" accompanied by the hashtag #sixmonths. Tucked between two stuffed animals, Crew sports grey sweatpants, a green shirt embroidered with his initials, "CG," and a full head of hair to accompany his new pearly whites.

Today, fans of the Gaines family were also offered another glimpse of baby Crew, this time perched on his mama's lap in a tan and white ensemble. The photo (below) was shared by Joanna Gaines as part of her annoucement that she has collaborated with her kids on a children's book, called We Are the Gardeners, chronicling the family's experience working on their garden.

The book lands on March 26th, but you can pre-order now for a limited-time only. We wonder when baby Crew will pen his non-fiction debut about life on the farm...
