Okay how much does this little one weigh? That is important to know b ecause the smaller the weight the more challenges there are.

Whose vet said it was okay to take home the puppy? Your vet? or the "owners vet'?

Introducing a new puppy to an adult dog. First make sure your adult dog is in a crate or separated somehow from the new puppy. Let them and the pup get used to your home first. Sniff, look, see.
Never and I mean NevEr let the two unsupervised in a room together. If you feel your older dog is now relaxed around the puppy - through watching their interactions through the crate. Put your older dog on the lead, and if you have another person in the home - they supervise the puppy. Allow them some time to sniff n greet each other.

Make sure your Lab knows they are not displaced in your affections. Play, pet , groom, walk your Lab as before.

It is your choice of course - but I crate my little Razz for sleeping at night. Our two very large dogs are on their dog beds in our room, with razzle in his crate beside my side of the bed on the floor. Obviously asleep I can't supervise their interactions, and although it's been a year now, if the big ones get up at night simply stepping of Razz could hurt him irrepairably.
