hi..I have a query I read somewhere that mothers milk loses its nutritional value if formula top up is given. my baby is breastfeed only but sometimes when m tired and Dont have enough milk we give him formula milk in only one feed in a day..its not very regular but as per need . 3-4 times in a week. please tell me if giving this can decrease nutritional value of mothers milk..my baby since was born premature m very concerned to built his string health. he is currently 3 months corrected age. please solve my query .also please inform how to monitor his growth..I understand that it needs to be counted from his corrected age. he is actual age is 5 months. also when I can start solids from 6 months or 8 month.
