German Shorthaired Pointer? ANY TIPS?

pest control including fire ants needs to be addressed.  Make sure you do heartworm prevention.  I really like a website called Holly's Den to get information before you are able to enroll in a puppy kindergarten.   GSPs are VERY high energy dogs.  You need to develop lots of play type games to play (but not chase the dog, it is too much fun and can interfere with recalls).  The two hose  (toy) game from ScH is great.  Get two equal/same toys.  Use them only for this game and no other time.  Slowly start tossing one toy a short distance (2 feet or less).  When the puppy has the first toy in its possession, use your voice, beating the toy on the ground, shaking and dragging the toy, to switch the puppy's focus to the toy in your hand.  When the puppy comes toward you, toss that toy in the opposite direction about the same distance.  Repeat about four or five times and stop with the puppy is really revved.  Then put it away.  You are building interest and drive for the toys and retrieving at the moment.  Over time you will have a dog who will charge after the toy, whip around and run back for the second toy, and if you have done it well, dropping that toy at your feet.
 
Do not do extensive road work (more than a mile of a steady trot; even that will be pressing it for a younger puppy) until 2 years of age when the growth plates close.  The running around, chasing toys, etc will be better than the straight line, trotting associated with road work.
 
Depending on the age of the stepson, have him do the training with supervision or modeling so it is done right.  Hand feeding part of every meal is an excellent way to help build a  bond.  especially if the kid lives in mom's house and only comes to visit.

Keep all phones, remote controls, etc. out of reach. GSPs are known for not only chewing, but actually EATING these things.

They are incredibly hard-headed, and can be frustrating to train. Keep your patience, and best of luck with your new baby!

Hard headed is right!!! But they tend to be very forgiving to your training mistakes.  Just be patient and they will just  soak up the knowledge. If you are rough with them they will just zone you out and you will get no where.  I wouldn't trade my shorthair for any other breed.  He never quits and he gives me 100%  everytime we go out in the field.  When they said that shorthairs were a versitle breed they were not joking.  .He is calm in the house, a lightning bolt in the field and a security patrol in the yard.   He has even taught me to be more patient in life.

? Ants? What do you mean I need to worry about ANTS?

I think mrv meant when you move to Georgia watch out for fire ants in the yard.  They can be extremely dangerous to pets as well as people.  I knew of a recurit in boot camp that was stung across their entire body from falling on to an ant hill.  Very nasty and extremely painful.

yup fire ants... they keep moving north

I am so excited for you.  I love my dog.  I got Abbi when she was 6 years old, so I can't help with the puppy stuff, althoug my dog has so much energy, most people we meet assume that she is still a puppy. 

Thank you Seashell! I am super excited! Although we got him for my stepson...(he lives with his mom) he will basically be ours, as we will be taking care of him, and lord knows I just love my doggies. They are MY kids! He has two little terrier mixes to play with and so far so good! He is so funny, they run around and wrestle...he tries, but he is SOOOO uncoordinated and clumsy still so its just so funny to watch! He's young enough that he sleeps alot! What I am absolutely amazed about is that he actually holds it! He goes in the crate at night, around 11 and he makes it till 3 or so when we go out and again until the morning. I came home at lunch today and he didnt pee in his crate, and again after work. Its amazing! And he seems to know what to do when he goes outside! So far only one accident in the house (this is only day 3, but still). 2 ALMOST accidents with poo, but its easier to catch before it happens. LOL.  I am just amazed because Bella, our 10 month old terrier mix had such a tiny bladder at this age! She peed every five minutes! We are STILL trying to housebreak her 100%, she is stubborn. What a relief Beau is! He is such a sweetie! Beautiful too! I couldnt believe how pretty he is. Or should I say...handsome!
 
Anyway, thank you all for the advice! Keep in coming! And for those who are thinking of advice on hunting etc...we dont hunt so he is for a family companion, not a hunting expedition, so I am seeking advice on making sure he is happy and healthy.

Here's a picture of the little guy

He almost looks like a Wirehaired German Pointer!
They are hard headed and head strong dogs. Require lots of training and always need to be kept busy. I suggest doing sports with him such as agility!
Good luck and he is adorable!

He's a cutie!  Recall, recall, recall.  When you have a minute, call him and offer a toy or a treat and when he comes to you or even looks at you treat him.  Make it lots of fun!  Play hide and seek around the house and when he finds you, really cheerlead and treat.  Consider clicker training.
 
He's a bit too little for agility (developing growth plates & all), yet, but puppy class would be terrific right now.  Take him with you to meet everybody and let him see all sorts of situations and environment.   
 
Also, set up a routine for eating, toilet duty, playtime etc. and try to stick to it. 
 
Remember that a tired puppy is a good puppy.  []

Thank you! I will definitely be getting into some training classes as soon as we get to Georgia. We are relocating in a month and I dont want to start classes that we cannot finish. Once we get out there, I will get him into a puppy class. In the meantime, we have had him all of 4 days and he is still acclimating to our terrier mixes, the new home, family, etc...but doing really well. A bit clumsy still, but he's a baby! He sleeps quite a bit, just as our other pups did at this age, and is really good with not peeing in the bed or anything! We have a schedule for feeding and so far only one accident and he stopped mid stream at my "eh eh outside". Almost had 2 poopy accidents, but caught it in time!

how adorable, what is his name?
You are getting a lot of good advice here.  Recall is very important for this breed of dog.  At home my dog is stuck to me, but outside, I am nowhere near as exciting as a squirrel, bird or even a leaf blowing across the yard. 
 

I find that true as well.  At home Hawk has a heart attack if I lock him on the other side of the baby gate.  But in the field he barely stays in the same zip code.  I worked long and hard on getting to come to me when he is out having fun.
