Staffordshire Bull Terriers and small kids

So my lovely in-laws got us a puppy for Christmas. And I say lovely in the most sarcastic tone possible. They got us a Staffy and I’m completely unsure of the Breed. Are they good with small kids. I have a 3 year old and an 11 year old. Also a tiny house which is why I was opposed to getting a dog in the first place. But here we are. So any advice, tips, even stories for your own experiences would be greatly appreciated.
