My baby's stool changes colour everyday

After this stage, your baby's stool will reflect her diet. If it is breast milk, the stools will be golden yellow, sometimes loose, even watery, sometimes seedy, mushy, curdly, or the consistency of mustard.  If it is formula, the stool will be soft but better formed than a breastfed baby's and anywhere from pale yellow to yellowish brown, light brown or brown-green. 
 

Will introducing solids change her stools again

The introduction of solids in your baby's diet will bring about some changes in her bowel movements. Expect her stools to become increasingly adult-like. A breastfed baby's stools will change from soft, mustardy, non-offensive stools to thick, dark, smelly ones. A breastfed baby's stools may remain somewhat softer than a bottlefed baby's up until weaning.
 

Should I worry if the colour of my baby's stools is startling.

The more varied the meals, the more varied the stools.  If you stop and think a minute, you can figure out the reason yourself. The scary red colour could be the result of beet juice. Sandy stools are fairly common and could be ascribed to certain foods like oats or cereals, which appear sandy after their journey through the digestive tract. Some baby food products have been known to colour stools such dramatic shades like fluorescent green and pinkish red. So do not panic.
 

There is not much difference between her meals and her stools!

Once they start solids, a baby's stools often reflect her most recent meal in colour and texture. So do not be alarmed if after giving her carrots for the first time, her next bowel movement is bright orange. Babies have immature digestive systems because of which much of what they ingest does not change very much on its way out. Foods not chewed thoroughly or those that are harder to digest may come out whole or nearly so.
