Deep breaths
. I promise, although it may seem aggressive, it's not - your pup just doesn't know how to act around you yet, and doesn't have either the restraint or self control not to bite/growl. It can be a slow process (weeks, even months) so just hang in there.
If she bites and snaps at your face, either stand up or turn around, fold your arms and ignore her. She will learn (slowly!) that biting etc = no attention. If she keeps it up then leave the room - or give her a short time out. A house line is good for this, so you can gently lead her away rather than pick her up (which could give her more opportunity to bite).
You can also redirect her attention to a toy. Keep some of her favourite toys back from her so she doesn't have access to them all the time, that will stop her getting bored of them and more likely to play with them.
Do you do any training? It's never too early to start, short little sessions (literally minutes at a time) that will help tire her out. Clicker training is great. Also give her food in kongs or treat balls (or little cardboard boxes - pups are always happiest when they are ripping things up
).
Don't worry about the cuddles - I couldn't even clap Brodie for the first few months without her latching onto me!
The toilet training will come too, but again it will take time as she only has a very tiny bladder. Take her out after every nap or playtime, and after every meal and drink.
Hope that helps, in a few months you will look at her and wonder how she could have caused so much trouble
. Take plenty of photos too, I was so stressed out that I didn't get as much as I wish I had, which I regret now. She will get there
