Are you breastfeeding? If so, you need to change your diet. Also try Gaia protectics, 5 drops a day, and you can find on eBay aeris gocce. Give it twice a day 0.5ml.
I think it’s caused by trapped wind as she’s only unsettled with it through out the nighttime and not in the day🤷🏼♀️xx
I’m going through this with my daughter also only seems to be at night time, I’ve been giving her a bath every night to settle her stomach, I’ve heard gripe water helps also xx
Comfort milk and colic bottles helped my boy x
Gripe water is good too x
Colic isn’t a diagnosis but a symptom that can be caused by a bunch of different things so it really depends on what is causing it - infacol might only help if it’s trapped wind, for example, won’t help if it’s caused by an upset tummy, an allergy / intolerance, reflux, something else causing discomfort etc. So need to try and work out the underlying cause.
