The TOWIE star posted the snap on his Twitter account simply captioned with a smiling emoticon.
Dan became dad to Teddy just before Christmas last year, and it seems he’s taking to fatherhood like a duck to water.
Teddy even made his debut on TOWIE, behaving impeccably as dad Dan attempted to coach pal James Lock over his relationship woes.
Following Teddy’s debut, Dan tweeted: ‘So proud to show you all my amazing son Teddy on tonight's @OnlyWayIsEssex... First baby to be shown on the show and he's perfect!! X’
He shared some more adorable snaps of his son, another with the caption: ‘Nothing better than seeing my little man smiling x’
Teddy’s mum is Dan’s ex-girlfriend Megan. She and the TOWIE star dated on and off for 18 months.
The couple split just before Megan discovered she was pregnant with Teddy.
Dan had started dating former TOWIE babe Lucy Mecklenburgh when he found out he was going to be a dad and the couple then split so that Dan could focus on his growing family.
Dan has since enjoyed flirtations with fellow TOWIE co-stars Jasmin Walia and Sam Faiers.
The TOWIE gang are due for yet another new arrival when Billie Faiers gives birth to her first child this summer.
