The 23-year-old TOWIE star shared a clip of his boy taking his first steps – and it's as adorable as you'd expect.
He captioned the video: "My boyyyy!! Before you know it daddy will be taking you to play football! [sic]"
Instead of going to the Sugar Hut for New Year's Eve, Dan spent it with one-year-old Teddy. And who can blame him?
Posting a snap of them together, he wrote: "Happy New Year from me and Teddy!!!! Could not think of a better way to spend NYE!!"
Dan is expected to become a dad for the second time within weeks, as his girlfriend Jacqueline Jossa, 21, prepares to give birth to their first child together.
After reportedly having problems with Dan's ex and Teddy's mum Megan Tomlin recently, it seems Dan and Jacqueline have managed to work things out just in time for the arrival of their bundle of joy.
After spending Christmas with her man, Jacqueline seemed to subtly hit back at Megan's alleged cheating claims with a simple picture of her and Dan looking very loved-up.
