Don't want to tell you how to suck eggs but from my experience, this is what I'd say. Sorry if it's a bit overkill.
Sounds a bit simple but puppy proof your place before they come. Anything you don't want chewed, make sure its off the floor. They will be inquisitive when they check out your home and the amount of times I've said they won't touch that and they have is unbelievable.
When you bring it home, if there is a blanket that his its mothers scent on, that will help it settle in your home. No big drama's if not.
Naturally your daughter will want to play all the time with it. That's fine. At that age they just can't control when they go toilet so just be aware when they are getting excited and worked up, to stick them out in the garden after 15/20mins of play to avoid accidents.
Just on getting them excited too, not sure how old your daughter is but they are very bitey when they are young. Tell her to be careful when she keeps waving her hands and fingers around its face, they just think your playing otherwise. Make sure they got some chewy toys they can play/bite into.
Make sure they go out first thing when you get up and before bed so they get used to going to toilet at these times.
Keep a couple water bowls out whilst they are getting used to things so they keep their fluids up.
I'm assuming you will probably get a crate for the puppy, which if you do, you want it to get used to going in there so don't sbut the door unless its at night so they can get used to walking in and out. Never make them scared to go in it though as punishment if naughty. Equally if they cry and howl at night, you kinda need to put up with it initially so they know your not weak.
Try not to mix up the diet too much because then they will get fussy and think if they don't want it, you'll just give them something else. There are certain things under no circumstance can you feed them, like human chocolate, grapes etc as its poisonous so familiarise yourself with these things.
Don't overdo it on treats initially, more as rewards for going toilet outside or when they learn to sit and stay.
They are going to have accidents, its natural. Just try be patient with that till they grasp it, and they will.
