Help!! Puppy problems

Bex • Mummy. Wife. Baby #2 due December 25th 😍👶

I have a 15w old pup who won't stop biting my 2yr old daughter. We have tried to get him to stop but finding it difficult. He has stopped biting me and my Other half as we can tell him no and he stops. When we say it when he goes for my daughter he doesn't listen. And she can't say no loud enough for him to understand.. Any advice?? Hes only bitten her once that has drawn blood but my other half has suggested to get rid of him to a friend of ours. The thought of it kills me and I cry my eyes out. I'm also 8w pregnant so am concerned he will bite the new baby when they areive!

Please any advice?? I can't part with him :( but I can't cope with him biting my daughter :(

Thank you
