The Splash! star, who is through to the semi-finals of Tom Daley's celebrity diving show, posted two new photos of Teddy on Instagram last night (27 January).
Dan is clearly loving fatherhood and couldn't stop gushing about his newborn. Captioning one photo, he said: "I love this little boy more than anything on this planet x."
In another snap, baby Teddy, who even has his own Twitter account, is pictured sleeping peacefully in his cot.
And Dan proved that he's mastered Teddy's sleeping pattern by telling his followers: "Happy Teddy tonight :)."
Dan melted the hearts of fans last week when he shared a photo of his son sleeping on his bare chest - and each snap just gets cuter!
Dan's ex-girlfriend Megan gave birth to Teddy on 22 December, and after announcing the happy news on Twitter, Dan described him as "perfect". Aww!
Filming for TOWIE's 11th series kicks off within the next two weeks, and we're sure fans will be pleased to see Dan back on the TV screen! In the meantime, the reality star will appear in the Splash! semi-finals, which will kick off this weekend.
