Carmen - my personal opinion is (and this is just my opinion so you can throw it in the garbage if that is what it sounds like

) -
Dog and Puppy diets are best left to the experts. A lot of time and research has gone into developing the proper balance of nutrients nescessary for the proper growth and development of our beloved companions. I fed IAMS or Eukanuba for years before doing some research and upgrading to Wellness. I personally would feed IAMS or Eukanuba over preparing meals which may not contain everything a growing puppy needs.
You can always add suplimental vitamins and minerals as per your vet's advice.
I know that with all the information available and all the premium human grade brands on the market today that people are taking advantage of the ability to put their dogs and puppies on "healthier" diets. Personally, if IAMS/Eukanuba was my only choice as far as manufactured diets - I'd feed Eukanuba. My dogs did well on it for years and years.
When it concerns a young pup - I believe that proper nutrition is vital - Maybe I am missing something here but I don't understand how you could possibly properly nourish a puppy on a home made diet.
I would not suppliment with Puppy Milk because once the pup is weaned even specially prepared milk products can upset the natural flora of the gut and cause gastric distress in the form of excess gas and diarrhea.
There are products such as Nutri-Cal (comes in a tube and looks like brown gel-like goo) that can provide extra nutrition, stimulate appetite and provide extra calories if the young puppy isn't eating enough. I don't know if these products are available in your part of the universe
Anyway - all that said - I'd seriously consider sticking to a manufactured diet. It is caloric consistant, and has the protien and fat content that keeps blood sugar levels stable and provides the nutrients needed for proper growth and development. Diet and nutrition can play a big part in behavior and temperament too. Fluxuating blood glucose levels can cause all kinds of problems.
The good old cooked hamburger with some boiled rice and canned pumpkin is a good way to suppliment and stimulate a poor apetite too.
I could be totally full of you know what

But that is just the way I feel.
I know you want the very best for your pup-to-be - just the fact that you are already considering all these things before you even bring him or her home is great.
OK- I opened my big mouth - and if I put my big old foot in it I apologize
