Hello Don’t worry you have rechecked the baby’s weight in a short span of 5days of which he should gain (5 x 30gms - 150- 200gms). There might be a calibration issue of the weighing machine for such small change.

Avg weight gain in first 3 months is more important than absolute. Its absolutely normal

Minor weight changes will not be noticeable on the scale. Do not worry about the number. Just watch that the baby is feeding qel, is active and passing urine 3-4 times a day.

Hello Just make sure that your baby is feeding well & adequate wet nappy these are more significant methods of learning whether baby is gaining weight or not …Dont worry about the number

Greetings It's common for a 1.5-month-old's weight to fluctuate or plateau over a short five-day period.Factors like feeding times, bowel movements, or slight variations in home scales can affect readings.However, consistent weight gain is a key indicator of health in young infants.Monitor for signs of adequate intake, such as 6+ wet diapers and regular bowel movements.Possible causes for a plateau include feeding difficulties, underlying illness, or natural growth lulls

Small day-to-day variations in infant weight can happen depending on feeding, urine/stool passed, clothes, and weighing machine differences. If the baby is feeding well, passing urine adequately, active, and otherwise healthy, a same weight over 5 days is usually not alarming.

Don't worry Daily weight should increase  30-40gm per day
