Hello, Welcome to HealthcareMagic forum. Perinorm tablet contains metoclopromide which being a dopamine inhibitor has a role in increasing breast milk production in lactating mothers. Apart from a healthy diet and metoclopromide many herbal or Ayurvedic preparations like satvarex powder, galactogogues etc are prescribed by doctors. But the best stimulation for increased lactation is suckling action of baby at breast , the more the baby suckles the more is the milk production. This will work best if the mother is relaxed, happy, bonding with baby and avoiding any stress. Also night time feeding, emptying one breast before offering the other breast to baby, using breast pump if there is excessive engorgement are all helpful measures to increase lactation in the long run. Most mothers fear of inadequate lactation but remember of baby looks satisfied after feeds, falls asleep, is growing well then milk production is most likely adequate. In your baby the growth is perfectly normal , all newborns do lose weight for first few days and then gain around 20-30 gm / day . The birth weight should double in 3-5 months . So as of now your baby is growing well. Hope I have answered your queries. Wishing you and your baby good health forever. Regards
