"Happy 4️⃣ Birthday Hudson 🎈. So sweet, smart and funny," the proud mom wrote in her caption. "He's always listening, watching and learning. He loves to help and ask Josh what projects they can work on together."
"He likes to stay busy and be on the move. Anddd he's pretty cute. We love you Hudson! ."
In June, Anstead shared an adorable photo of Hudson after he graduated from preschool. Wearing a blue cap and gown, Hudson smiled and held up his promotion certificate.
"Oh WOW how that year has flown by," Anstead began his caption. "Today I was met by one very excited little boy who was desperate to share his end of year school book and certificate!"
"He was so proud! And so am I at how far this little boy has come this past year! He's truly thriving and glowing! X," he concluded the post.
Last year, Hudson had a special part in his mom's wedding to Hall. The HGTV star shared a sweet video of her two sons, Hudson and Brayden, as they walked her down the aisle at the picturesque event in Maui, Hawaii.
The two boys walked on either side of her, with Hudson holding her hand, as they made their way down the aisle, which was lined with white flower petals.
