I had two kids that lost thier mother at 2 days old.. I went and got some sav-a-kid and brought them inside. they were doing fine for 4 weeks. i was mixing as directed. i was letting them stay outside (4 weeks old) and I increased the mix as directed to 4 cups of power and 3 cups of water... I fed them that day and that night gave the 10 oz.. the next morning the girl was swallen and died. the boy was fine and i went back to 2 cups of power and 3 cups of water... He now stays sick 90% of the time... When he feds if he takes 10 oz he will just stand there and cough... he did swell up and i gave him gas x and cut the mix back to 1 power and 3 cups of water..... he has diarea almost all of the time and looks like the is loosing weight..... he is 6 weeks old.... he does play with the other kids, but i do see a change in him.... what sould i do???
