You are very welcome.The average weight for a baby girl of 13 weeks is 5.5kg. Your baby's weight is below average and falls on the so-called 10th percentile line on the Infant Growth Chart. This means that her weight is in the lowest 10% for baby girls of her age.She should be taking about 720ml of formula per day which she is not doing. She may still be refluxing and may need more in the way of treatment, possibly using Losec and Domperidone. Speak to your paediatrician. Once her reflux is properly managed you can see if she feeds better. If not a change of formula to Lactogen 1 may be something to try.
