It is cute, our Peanut did that too at first. They will do it much, much more when they start teething badly and start nibbling... If you let them... You have to limit the amount that you let them do that. Start pulling your hand away a little and ignore it and give a toy, bone, or something instead.
Don't let it become a very bad habit... they are most impressionable when they are younger and will decided that it's ok for the rest of their life...
It's tough love, but you gotta do it |
