my preemie with birth weight 1590 now is 4 month old......... now weight is 4 kg.... she is on complete breast feed........ is weight gain appropirate Or should I give other milk

A. Hi parent You MAY give formula as per your pediatricians advise. but , better to stick to breast milk if your BM supply is apt. try to improve your BM supply by taking nutritious diet as well as good amount of water. but don't use demineralized water use simply purified water having tds higher than 350
