I feel bad that due to improper counselling parents often do weird things with their beloved babies. Upto six months of age, exclusive breast feeding is recommended. I am surprised that someone has recommended powder milk. The focus has to be to increase mother's milk and keep the baby on breast as long as possible.Even water should not be offered to the baby.The mother should drink extra water/liquids like juices/soups etc and keep herself well hydrated for optimum milk production. Also she should take a wholesome diet and never worry that her milk is not sufficient for the baby. If the baby is passing urine frequently, passing stool 6-10 times per day and gaining weight
, breast milk production is enough.
regarding sleep pattern, it is a very good thing that the baby is sleeping 7 hours at a stretch. The baby should be awake during the day and interact with the environment. Dont worry. Sleep patterns change. Your baby will start sleeping during the day too.
