Help with breed of dog for children

[amatuermummy]

I feel a bit silly asking this as I have shown and trained dogs for years, however we all tend to stick to our own breed and I need some help picking a breed to own now that we have young children. I prefer big dogs but don't think it would be a good idea to pick a large breed with a baby learning to crawl/walk and a 2 year old running around. We would like to get a small/medium breed that is good with people - especially children. We've researched breeds, looked on breed websites and spoken to some breeders but it's hard to know if they're just trying to sell you a puppy. I just wondered if you wonderful dog owners of mumsnet could give me your experiences, good and bad, of small/medium breeds to help us make our minds up. We're in no rush or anything and will obviously take our time choosing.
The reason we will not be getting a rescue dog at this time is because, having worked in dog rescue for many years, I know that most will not home dogs with young children and, also, I do intend to show the dog as a hobby as I have done this for around 20 years (mostly handling other people's dogs for the past few years).
Thanks for your help.

must be from a puppy so you can imprint early, I have a yorkshire terrier, but snappy, also a cross jack and schnauzer, has always been good never snappy and friendly with dogs she meets, I think this might be the schnauzer in her, and she is 14.

My boy is a working cocker. He is utterly lovely.

Our springer spaniel is just gorgeous with our 19 month old. She's only 6 months older than him and they adore each other. I honestly don't know how we would get through the day without her sometimes as she provides hours of entertainment for him. He climbs all over her and she never has a go at him, just hides if she's had enough!

Whippet. Scruples Whippet rescue do rehome to homes with children, they use foster homes too, which helps assess the dogs accurately. The lady who runs scruples has also been a crufts judge for whippets too iirc.

I have a male labrador he + my daughter are best of friends and he is so paitent and gentle with her I would never have another breed around children other than labs or retrivers but I do believe children + dogs are a blank canvas and they are what u make them so I'm sure any dog will fit into the family if it is trained + treated right. I do find smaller dogs are snappy and yappy tho so would shy away from smaller dogs
