Hypoallergenic milk

JJ

Does anyone use hypoallergenic milk? My lo is so difficult to feed, giving her a bottle is such a fight. She’s gaining weight as she should be - she’s 10lb 2oz and 9 weeks old but screams so much during feeds. We’ve tried lactose drops but they have made her poos like water! Just wondering if anyone else has this? I’ve also tried comfort milk but didn’t make a difference along with anti colic bottles
