Hi Siri feel your sons weight gain is almost near his expected for his age(according to our calculations).you can continue soil as it is a perfect substitute in kids with CPI. But I would recommend you the following dilution...just check if you are correct... Dissolve 1 scoop of powder(the measuring spoon given by the product manufacturers) in 30 ml of lukewarm water. You can give 100 to 120 ml per feed for your sons age...which means 3 1/2 to 4 scoops in 100 to 120 ml of water respectively...you can give 6 to 8 feeds per day in addition to breastfeeds as and when required. But make sure your wife is off milk products in all forms after having a confirmation with your doctor. If the country which you reside is tropical or hot at present, you can give 2 to 3 spoons of boiled and cooled water 4 times a day. Normally we don't advise so in exclusively breastfed kids but because your son has already been started on formula feeds I'm advising you this way just to make sure his water content is also adequate. I would be glad to help you further if needed. Chat Doctor.  V.Pediatrician
