So Navi is pretty comfortable in my house and with my family and always asks for attention and for us to hold her. She's a good girl 98% of the time but recently out of no where she'll start biting all over our shirts and i think she mistakes our skin because she'll nip painfully at our necks and faces. I usually will warn her with saying "hey, you behave" or "be gentle" and she'll look at me and move on or do it again or just do it another day. I feel like it is starting to gradually happen more. I just don't want this behavior to become more frequent so how can I stop it at the beginning? I usually will put her down to show her that she wont get my attention if she does this, but is that the best thing to do?
I also take into consideration that she is a baby (2 monthsand a half)and is probably just trying to experience the world around her.
Any input will be appreciated.
