#AskTheExpert Doctor, I'll a my 8 months old for the paatvone week has trouble falling asleep during the night. usually when we carry him and walk and sing lullaby however bad his mood is / condition is he used to sleep. Now for the past one week, nothing works. He screams and cries and he is inconsolable. seems he is uncomfortable, in pain etc. what could be the reason ? He is mouthing a lot these days and for the past two days he cries a lot half way through his solid feeds.. also he kind of puked two times since yesterday.
