Footage of a US family with 13 children getting very excited when their parents announce yet another new baby is on the way. <br /><br />The video, captured at a home in Muncie, Indiana, shows the children wearing a t-shirt with the word "chicklen" (the made-up word the father uses for calling his children) and their birth order number written on it. <br /><br />The dad opens a gift bag and unfolds a babygro that reads "Chicklen 14."<br /><br />When the children realise they are having a new sibling, they can't contain their joy. <br /><br />"I called it," says one of the girls. <br /><br />"Mum you're pregnant!" says another one screaming. <br /><br />The mother later wrote online: ''After 22 years in the navy we decided we were done with having kids.''<br /><br />''Well, here we are 18 months later and expecting baby 14.'' <br /><br />''We decided to tell the kids we wanted to update a family picture with a theme this time. So I bought the kids a t-shirt that said 'chicklen', along with the year they were born.'' <br /><br />''They all opened their gift bag and put on their shirts. Then dad opened his,'' she continued.<br /><br />''The kids' reaction is priceless.''
