Puppy's first foods

Hi all,
Ok for those who don't us on here; We have 10 healthy puppies that are now 5 weeks old they're Argentina Dogo cross with StaffordshirreTerrier. 8 of the puppies have been with the mother, for extenuating circumstances we have 2 of the babies with us away from the mom, they have been hand bottle-fed since birth since they started needing more and more formula at each feeding, I figured it was time to start feeding them solid food, so a few days ago I started feeding them some wet food, and just a small bottle of formula with each meal, along with a bit of water still in a baby bottle so they aren't drowning in it. While it will be near impossible to regulate the amount of food intake with the babies that are still with the mother, the two we have with us will be easy to regulate; so here's my question;
Is there a chart for feeding amounts? like ounces of food per pound? / per feeding? etc.
trying not to overfeed them and cause any problems internally.
Thanks in advance all!
