My 2nd baby is 2 month and 1 week old... since 3 days he is not able to sleep during daytime he is feeling sleepy he closes his eyes and sleeps but within few minutes he wakes up and starts crying... if I put him on my shoulders he s sleeping if I make him to lie down on my lap or cradle or bed he starts crying.. aftr 5 r 5:30 only he is sleeping without crying... there is no motion or urine problem... why is he behaving this way?? Is there any solution??
