Hello Doctor , My son is 7months old now. From birth he keeps crying in the day and night . Around 4months it was slightly better . But now again he wakes up in the night and cries suddenly multiple times , though I feed him every 2hours thinking he wakes up in hunger .Once after fed he sleeps for 30mins and again wakes up and cries .Could you please help me what could be the possibilities of his crying ? Also is it okay to feed him every 2hours in the night ?
