My 5 months old baby is making straining sounds as if putting pressure to pass stool. This he continues almost whole day when awake. He stiffens his body and legs while doing so and sometimes turns face red. If i hold him and walk/distract then he remains fine. Otherwise, he keeps making this sound intermittently but very frequently. We are giving lanzol junior tab and domstal from 1 day but no improvement yet. Had the same problem 1 month back but with same medication he felt better. What exactly is the problem? Other than GER what could cause this?
