Breastfed vs Formula-Fed: Does Feeding Type Change How Many Times Newborns Poop?
Feeding type is one of the biggest factors behind newborn poop frequency.
Breastfed babies tend to have different stool patterns because breast milk leaves very little solid waste to be eliminated. Stools are typically soft, mustard-yellow, and seedy in texture. After six weeks, some breastfed babies may go four to seven days without a bowel movement and still be normal, as long as the stool is soft when it appears, and the baby is comfortable, feeding well, and gaining weight.
Formula-fed babies generally follow a more predictable pattern, with one to four stools per day. Their stools tend to be firmer, paler (tan or light brown), and more formed than breastfed stools. Formula-fed babies rarely go as long between movements as older breastfed babies, so more than two to three days without a stool warrants a closer look.
In the first month, breastfed babies often poop more than formula-fed babies. After six weeks, the pattern can flip, with breastfed babies going less frequently while formula-fed babies remain more regular.
