Brian Austin Green is ''an amazing dad''.Brian's wife Megan Fox gave birth to the couple's first child Noah in September and the actress revealed her spouse has been wonderful with the tot. She said: ''He does anything that I can't do at the moment because I'm too tired. Whatever's going on, he does. He's the perfect daddy. ''Noah is getting really chubby! ''He's super healthy and funny and he's very bossy already. He's got a very strong personality, so I'm really in for it!'' Brian, 39, also has 10-year-old son Kassius from a previous relationship and Megan revealed they can't wait to have even more children. She added: ''I want a big family. I definitely want to have a couple more kids.'' While the 'This Is 40' actress has already lost 13 of the 23 pounds she gained while pregnant, Megan doesn't feel ready to start working out yet. She told Us Weekly: ''I can't work out yet because my body is still too fragile. I try to eat whatever I want, but I don't eat any dairy, and I guess that's the biggest diet tip. Try and stay away from dairy -especially if you're a woman! It's really hard on your hormones.''
