It all just depends on the animal. Some will have no wobble as babies then get one when they are older and some will have it as babies and grow out of it, some will show little to no wobble their whole lives. It all depends. Severe wobbles aren't super common though so I really wouldn't worry about that. Yeah they are a big quirky but for the most part they live normal lives and eat just fine.

My girl has only shown a wobble one feeding when she got really excited, but the most it did was cause her to miss her first strike and have to try again.
