I was today prescribed Nutramigen for my daughter Anna, who took an allergic reaction to Aptamil (I'm try to move her at least partly onto formula, as I return to work next month). On the tin it says to boil fresh water and let it cool to room temperature prior to mixing. Assuming that "room temperature" means around 20 degrees celsius or less, this seems much cooler than what is instructed for more standard formula (over 70 degrees?). I just wanted to check that people do actually let the water cool down that much. Also, what temperature do you serve it at? Would it be OK to heat it up to body temperature? Thanks
