I'm not from us so might not be very helpful but I'm guessing the nutramigen one is an allergy formula like in the UK I'm unsure of what products are available to you but here we have thickeners such as carobel to help thicken allergy milks due to them being super thin Sorry if it isn't helpful
Try Nutramigen it’s a step down from that one. We had the same issue and my son did not like the aluminum one at all, but we still needed something that had the milk proteins broken down. After about two weeks on Nutramigen he was good to go!
Only best option is to talk to your baby’s pediatrician and see what they recommend
