Nutramigen 8oz rtf out of stock

My baby is on Nutramigen rtf as powder didn’t work for us much. Currently i cant find anywhere nutramigen rtf 8oz bottles. Its hard to go to the fridge and then somehow warmer the 32oz ones. Do you know why its everywhere out of stock? or its showing to me? (leaving in PA). I dont know what to do. Also she will be 1 year in 2 months and i cant find Toddler version anywhere. I am so depressed
