No mp is too stringy for newborns. I find it's best to start them on live blackworms or frozen bloodworms and then after 2-3 days of them eating that start them onto a canadian nightcrawler cut into 3 pieces and after they start eating this for a week start adding in a piece of broken carnivore or h20 wafer for one of the meals. The bigger the pup the quicker it is to switch over to new foods. Mp seems to take the longest to get them onto.
