Yeah, that does sounded like a little crazy idea and question. But apparently, it’s not. At least not for this person that asked the question.

My first reaction was, why would anyone want to feed their bearded dragons Gerber’s baby food? So I googled and make sure that bearded dragons is what I think it is and sure even here it is. Yep.

Look at that smile. Maybe he could win the next Gerber baby contest?
Well, he is an omnivore which means he eat both meat and vegetable. So we’d assuming that it is safe for him to eat baby foods. Maybe it’s a good idea to have other diet as well and using baby foods as supplements?
