Reasons of First Week Weight Gain/Loss in Babies:

Usually, healthy newborns are expected to lose around 8-10% of their birth weight. This is because:

Some more factors that can contribute to losing weight in infants are:
• sleeping more and feeding less
• sickness in the baby
• mother’s health
• stress/anxiety in the mother
• if the mother is pregnant or on contraceptive pills
