4 month old breastfeed but topped up with formula before bed, feel like they're constantly puking. Sometimes they get really unhappy and do lots of back arching, or will be squirming around at night. Dr prescribed gaviscon but aside from pastey poos I'm not sure it's done much. Often in sling or held upright but also likes being on tummy.
I had horrible reflux in pregnancy so I just feel so sad for little one going through this.
Anyone have anything the worked?
