super trusting kit

Hi I recently just saved a baby chin when he was 8 weeks old. He is now 13 weeks. And ever since I brought him home he's trusted me from day one.. he comes right up to me grooms me all the time let's me hold him loves his chin ear n belly rubs he will take a chin rub for half hour if he could. He loves to jumps all over me n loves my kids. When I let him out for freeplay he will come right up to my toddler jump all over her n start nibbling her toes n hands so gently.. I was wondering is this normal for chinchillas. Or at least for kits
