You have a beautiful beardie that isn't afraid of food. At that age they're growing up & out so fast there's really no such thing as a too fat baby. She's going to have a big growth spurt about 5-6 mo, you'll see her slim down, then chub up again. I have 5 beardies, all adults & they go up & down in weight. Leo is our chub, but he'll lose 100g in the spring (male madness time of year) & then gain it back in the summer. So don't worry. I wish we got dubias in Canada (they're illegal) as they are such good feeders. She's a really healthy girl, too.
Where so many owners are asking why their beardies aren't eating, you're asking if your beardie is too big. No such thing, she'll grow into her weight soon enough.
