What you are describing, evening crying that is hard to console and restarts within minutes of settling, is a classic colic pattern. It is common at this age and usually eases by 3 to 4 months. It is not usually a sign of anything more serious as long as he is feeding well, gaining weight and passing stools normally.
Next Steps
Whether Colimex is appropriate for him below its labelled age needs his paediatrician's judgment, not a fixed rule, so please check with them directly. Meanwhile try swaddling, gentle rocking, white noise and holding him upright after feeds.
Health Tips
See the paediatrician sooner if he develops fever, feeds poorly, vomits, or isn't gaining weight.
