The first 3-4 pees he had it. I was told that it's crystals and does signal that the body isn't getting enough fluid, but it's pretty typical very early on. I know after the fourth pee his urine was pretty clear.
From Dr. Sears-
The color of the urine tells you whether baby is getting enough milk to keep him adequately hydrated. Pale or water-colored urine suggests adequate hydration; darker, apple-juice-colored urine (after the first four days) suggests that baby is not getting enough milk. If your baby is not getting sufficient amounts of milk, you may notice a "brick dust" residue on the diaper, due to urate crystals from overconcentrated urine (a normal finding in the first few days), which should disappear after increasing baby's milk intake. Talk to your doctor to determine if your baby needs extra milk during the time he is learning to breastfeed more efficiently.
