If it is firming up after the first dose you may want to give it a little more time before you redose and see if that continues.
Give him some additional hydration between his feedings to help replace what he is pooping out.
What does he weigh? Is his tummy completely flat when you feed him? If not you may want to wait a little longer between feedings. You want them to completely digest and empty out before you feed again.
