#asktheexpert my wife is not producing milk so isn't able to breastfeed my son since his birth. initially she did produce it for first 3 months but we have been feeding him Similac formula milk till not when he is 6 months n 20 days old. my concern is that Similac and these formula milk is getting more expensive because now it's being sold for 600. it just last for maximum 4 days. We are not able to afford it. please suggest which milk we should go for?
