Hi has anyone actually do the re challenge and been able to get there child back in dairy. Starting the challenge today and I'm not 100%. If my baby has an allergy or not. He's currently almost 4 months and been on a dairy free formula since quite a young age due to sick and crying. He is also on meds for reflux and has a tongue tie so I'm not sure if that is what was causing the vomiting early on not dairy.
Thanks Amy
