I had the same problem, and the doctor recommended that I alternate every feed Infacol and Colief and also give her probiotics every day. I gave her probiotics for three days, and she has been a different baby since. I don't know if it is a coincidence or if it actually works.
Colief drops= miracle
@Georgiana Aura what probiotics did you use please?
From BioGaia, baby drops
My first had bad colic, we bought her a wedge for her mattress which helped, being on her tummy helped too, so on me or my psrtner and tummy time. We also used infacol before bottles. I know there's something the docs can prescribe if it's really bad. We got told to buy a wedge from the health visitor. I know sleeping on the side csn help too, like putting yoyr t-shirt behind their back so they don't roll on their front but are enough on their side :)
