Infants usually adjust to a hypoallergenic formula and settle into a routine after a few days or weeks. The same may be true when adding prebiotics and/or probiotics to the diet—a gradual transition may help.
The research behind Neocate Syneo Infant suggests that there may be some initial changes in stool characteristics (e.g., color and consistency) during the early transition to this product from a formula without pre- and probiotics. Stools may be softer, more like breastfed infants. In the first days/weeks of use, your baby may also have more gas or flatulence, which may cause some temporary discomfort or fussiness. Talk to your baby's doctor or other healthcare professional about the need to transition gradually onto Neocate Syneo Infant.
When a baby is on Neocate, the first stools tend to be green and can be dark - a lot of parents describe the color as hunter green (but contact your baby's doctor if the stool looks black, which could be blood in the stool). Green is completely normal (Green is Glorious!) and is due to the special composition of Neocate and the way it is digested and absorbed in the body.
For most babies on Neocate, the green color will last for at least the first few days. It may fade after several weeks, but for some little ones stools will be green as long as they're on Neocate. Often stools will change to a yellow/tan/khaki color if the green fades. This is normal, and is a result of the body adjusting to the way Neocate is digested and absorbed. Color can also change when solid foods are introduced into the diet.
The consistency of stools for babies on Neocate tends to be soft and somewhat pasty, though this can vary. For some babies the stools will be looser, and for others more solid or formed. Again, adding solid foods to the diet can affect consistency. Mucus in the stool is not typical so if you see this, you should let the physician know.
Neocate Syneo Infant is a specially formulated medical food and should only be used under medical supervision.
