The 23-year-old uploaded a snap to Instagram, showing that nine-month-old Teddy had picked out daddy's calendar while shopping with his nan.
Proud dad Dan wrote: "Teddy saw daddy while he was out shopping with nanny today. Bless him"
Dan is due to become a father for the second time next year when his girlfriend Jacqueline Jossa, 21, gives birth to their first child together.
So we can expect even more adorable snaps of Dan with his children, then!
Meanwhile he recently spoke out about appearing on the Essex reality show, insisting that if others had the chance they wouldn't turn it down.
Speaking to Attitude magazine, Dan said: "I don't really get any stick, but people think you haven't got any talent and you can't do this, you can't do that, but the truth is we've all be given an opportunity and just taken it.
"You're not going to turn it down, so we're just the same as anyone else. You get a lot of people saying 'Oh I got offered it and turned it down,' which is a total lie."
Speaking of his children, Dan admitted he never expected to have two by the age of 23.
He said: "The second's due in the New Year and obviously it was a surprise but I wouldn't have it any other way. I absolutely love being a dad and I always wanted a big family. I always wanted kids at t a young age too."
