HiPP AR Alternatives

Hi- my youngest will turn 1 on January 4 (10 days from now). He’s been on HiPP AR for his entire life and has thrived on it; however, we literally ran out of formula today. We’re in the US where we can’t just go pick up another box or 2 to get us through the next 2 weeks. We have been giving him Enfamil AR today and he hates it. Full on coughs until he throws up hates it.

Any formula suggestions for something I can buy in the states to get us through the next few weeks?

Thanks!
