hi all.
  had our staffie puppy 2 weeks now,she is 9 weeks old and the whole family adore her,our only problem is she constantly bites us and our kids,so much so my 6 boy year old recieved a bad cut on his ear and had to go to a+e to have butterfly stitches (although we're not quite sure if it was her teeth or claws that caused it)she gets plenty of love and affection from the whole family but does tend to nip our kids(twin boys of 6,girl of 10) more than me and the wife.
we've used various technics we've read and heard of,namely immitating the 'yelp' of another puppy and shouting 'no bite' also placing our hand on her back and squeezing to replicate a mothers bite,which is probably the most affective although i really dont want to use that method too much.
im aware puppies to nip bite and mouth however you want to put it,i just want to remedy this problem a.s.a.p so the children especially can enjoy her at this age without us worrying about if our pups getting too rough with her teeth.
your advice and expert opinion greatly welcome

This is the best article I've read on the subject. I've followed it myself several times and it does work. Stick with the yelping and leaving the room or turning back on pup. She'll soon realise that if she wants to keep playing she'll have to be a little kinder I really wouldn't use the pressure on the back, particularly because the kids are likely to try the same thing and may inadvertently hurt such a young pup.

thanks,my point excatly on the pressure tactic,she is more or less fine with me,she does nip the wife on occasions but especially the kids,im assuming shes trying to find her place within the 'pack' and our boys are the easy target because of there size,but hey,thats just my opinion.
she is hard work but even after having her for such a short period i could'nt imagine not having her around,we're just keen to get past this stage in her life

> does nip the wife on occasions but especially the kids,im assuming shes trying to find her place within the 'pack' and our boys are the easy target because of there size,but hey,thats just my opinion.

kids are soooo much fun for a puppy (and adult dogs), they have squeekyer voices, quicker movements, much more fun than a sluggish adult

We had a MAJOR play-biting phase with our pup and he blinking hurt, it was quite scarey at time because he was so big. The 'yelp' noise or an 'ouch' only made him more wound up, as would pushing him off - he would take any rough-ness as play and come back even harder, so we followed 'the bite stops here', but swapped the 'yelp' for a calm 'no' (not shouted). If pup was still being a biting machine after that I would gently hold his collar and lead him to the kitchen, where he was shut in for a few minutes to calm down, at one stage I would clip his lead to his collar to move him otherwise he would try to bite my arm!!!. Another thing I did was offer a toy for pup instead of the peron he was biting, to give him an alternative target when he felt the need to bite things, if he didn't play with that and then ignored a 'no', he would then be taken to the kitchen.

The biting can seem like it's never going to end, but as long as you're consistent you'll get the message across. Staying calm and not shouting, really does help

The article Tigger2 mentions is excellent. Just one other point here as you said:

also placing our hand on her back and squeezing to replicate a mothers bite,which is probably the most affective although i really dont want to use that method too much.

a bitch would NEVER hurt her pups, they never get physical at all, all reprimands are done with body language only, so to try to do this would be very unnatural and could definitely make matters worse in many ways.

Glad that your children are not toddlers and you have been very sensible in getting your pup when your children are older. The best thing about them being older is that they will listen to you and learn how to behave around a puppy much better than a younger child.

Pups do bite, scratch, drag, I'm glad that you realise that is normal puppy behaviour, trouble is children as already said are the main targets for play like this, even with the document supplied to adhere to (excellent piece) the best way to protect your children is for you and your wife to be the playmate, not your children.

My children helped to train my girl, they were the ones with the treats teaching puppy to sit, down, stay, roll over etc, enjoying our walks together etc, that was their roll, they had pup sleeping on them, greeted her, cuddled her fed her at times and that is all that they did, when pup was calm she was theirs with my supervision, when she wanted to play or started nipping I took over that roll and removed her from my children as pups hurt. If she was having a mad 5 minutes she was put over the dog gate with her toys and she could have an energy burst with my children safe.

Puppies grow up and of course your children love your girl, but you need to protect them both from each other, so talk to your children about the fact that the pup needs to be segregated from them at times to keep them safe and you need to take on the roll of playmate and keep her from nipping, scratching and pulling your children around, pups are little devils and children hurt easily, yes they are cute, but pups are far from the image of cuddly teddy bears, they can become 'family' dogs when older and your in control of them with STOP! and other commands to help a dog to live with it's humans.

You can control a pups behaviour by teaching it commands, but you can't stop it, it's natural, especially at this age, so just remove the pup from your children and take over the roll of playmate.

As a dog owner who had pups from when my oldest was a toddler and then my second pup when youngest was a toddler and oldest pre school I agree with everything Carrington has written.

Pups and children are not suitable playmates and need protecting from each other.

Any interactions are only when both are calm.

In addition to what Carrington has written my first pup was taught that if children were near at home or on walks she must come to me and lie quietly by my side.

My first dog was of a Medium herding breed, so the above was very important, and my current breed is a muscular sturdy bold and energetic hunting breed who are excellent with children, but can easily knock them over.

As Staffs are 'canine cannonballs' I would say the same applies to yours.

thanks to all those who have replied,all comments,suggestions etc have been greatly welcome.
we will endevour to continue training her as suggested,no doubt i will be posting more questions for advice etc real soon/
i have tried to download a picture of her on here for all to see as she's a real beauty,but it keeps coming up with 'error'.
thanks again for all your advice

oh i cant wait to see her, im sooo jealous, i want a puppy!!

i agree with everything that has already been said but would add that one thing i told my boys to do with our pup is when they are getting excited and nipping to get a toy and give it to the pup to replace there arms and play with pup and toy this has been very effective , this way the kids can still play with pup without being hurt.
