My baby is 4 month old and in FM ONLy frm last few days my babies sleep has been reduced as he is sufferting from colic abd treatment is going on. But now a days baby keeps on crying while putting him on sleep. Though he is sleepy he will not sleep n keep on crying. Intially he had the habit ofsleeping on hand n recently on lap.but now he is not ready to sleep n leeps on crying hv trird rocking, swing swaddle everything. Nothing is working out. The prob is with day at night also he will sleep crying only but sleeps properly.

Plz suggest what should be done
