I'm not sure my beardie is growing as fast as she needs to. Every beardie i have seen her age is 10+ inches already and she's a whopping 6 1/2 inches at (around) 4 months.
Can this cause any health problems in the future? She seems as healthy as can be at the moment.. just a bit tiny.
my little girl was 6 1/2" at 6 months. i did everything right and she got fed good, then at 6 months to 9 months she grew 9 inches long. Some just take longer to grow. As long as you do everything right, have the right lighting and so on, he/she just might take longer to get the growth spurt
