In my experience, which is limited to my current 8 month old pup, he loves people. My mother for example was here the day we got him than we didn't see her again for a month and we see her maybe once a month sometimes less and the pup adores her. The same could be said for my in-laws nephews nieces cousins. I think if I were you I would not worry. What I can warn you of is the training. We have taught the dog Off for Jumping and Down for Lay Down. Every single person I know says down for off. My pup less then half the time will actually lay down when they say down. Keeping your husband informed of the rules, boundaries, training words and methods I would think important to maintain consistency. I have come to learn the importance of consistency.
As for the pup and kids I don't know the ages of yours but I think it makes a difference. I think it also matters how much experience you have with dogs.
I have kids come over often and I have two of my own 5 and 12. Getting the puppy to the point of being calm or even how to interact with excited children has been a challenge and at 8 months he is doing pretty good. He is still a little to pushy for kids 4 and under. Kids can run in the yard or house and not get nibbled on or bitten or jumped on. He may bump into them or give them way to many kisses. I say challenge because for me it is my first dog and I have a lot to learn.
If I am honest my puppy was so mouthy the kids did not spend much time with the adorable puppy. We made it a point everyday for the kids individually while supervised to pet or play with puppy with toys. The moment he put teeth on them the play time was over. Our puppy was so bad that if I let him he would jump on them and bite them with those razor teeth and make them cry and he would not care. The first 5 months were really hard for us. It was a lot of work, reading, and effort on our part. My husband is a stay at home dad and I work from home we put in a lot of effort. Someone who knows what they were doing with the amount of time we had could probably have done a lot more LOL. We had to keep the pup active and engaged so he was not crated to much while rotating the kids so they were not jealous of the puppy. All that said it was a small price to pay for the wonderful dog he is becoming. I am really enjoying 8 months he is awesome.
I can not express enough how valuable crate training was to us and the importance of it being a place the puppy loves. We still use the crate. Having a safe off leash place or some where you can use a long line for the pup to run his heart out that is NOT a dog park is really important too I think.
Best of luck to you and welcome to the forum.
