Is this CMPA or reflux

[BePearlPoster]

Hi so I have a 1 month old and over the past 2 weeks she’s been experiencing signs which I thought was reflux but I’ve come across CMPA and now i’m thinking is it? her symptoms are a lot of spit ups, saliva, baby acne, mild dry skin on forehead, foul smell poo, very very unsettled, struggles to nap, sneezing, snotty but we thought the sneezing and snotty was a cold, we have been trying gaviscon but I feel like it’s making her worse any advice?

My eldest had this, one of the biggest signs was very mucussy poo and crying an excessive amount (like more than 3 hours a day of screaming). She was diagnosed but then was officially diagnosed via skin prick at 12 months, and has just outgrown it now at 5.5 years. We have a 6 week old and I questioned it at around 4 weeks but he’s settled now so I assumed maybe a developmental leap and slight reflux. The crying with CMPA in my experience was more than fussiness. Is baby BF or bottle? If BF there’s no harm in going dairy free and see how you get on, it can take about two weeks to see a difference sometimes x
