At first my baby gained weight fast from 4th may to 17th june she gained 2 kg... her birth date is 4th may... birth weight 2.188... but from 17th june to 25th july she gained only 600 gms... is this normal..?? I feel she has feeding problem as she breast feeds then sleeps and again after 20 mins gets hungry....but does not take formula milk neither by bottle nor by katori.... she used to drink both breast feed as well as formula... is she having reflux??
