Sure. So is brown, light yellow, and seedy mustard. These variations in hue depend on whether your baby is drinking formula or breast milk (and, in the latter case, whether her bowel movement comes from fore milk or hind milk). You can ignore the color unless it's white and chalky, thick and black, or red. These tints could signal an illness, so let your pediatrician know right away.
You should also avoid fixating on how often your baby goes, whether it's ten times a day or a few times a week. A more significant marker: She should have at least six wet diapers a day, which indicates that she's well hydrated and getting the nutrients she needs.
