I remember this too- I wore gloves for the first few weeks as my hands were so sore...and the same old jumper that had holes ripped in it...
Oh- I am so with you!
I lived in the kitchen (almost) for what seemed like weeks, and the stairgate was the saviour to my own space (although not for long while the house training was going on...
)
I was beside myself on some days, but had lots of help & support from the lovely posters on here ..so hang in there!!
9 months in, and the biting has almost stopped, and my clothes are no longer in shreds (although Daisy does still have the wrong type of shoe habit....)
I also agree with the PetRemedy stuff that Archiebean suggested..I tried it on her recommendation and it does make a difference.
"Time out" also helped..ironically, I was trying to tire her out, and as others have also said, was making the situation worse...now I realise when she is "overtired" (which is normally when any mouthing now starts)..
Persevere- you will get lots of invaluable help from here
