Sleeping problem. I have querry!

I have querry regarding sleeping problem of my baby I have been observing him for past 15-20 days. He doesn't sleep early . He needs breatmilk to go for sleep. After that he not sleeps then my wife put him down on her lap and keep trying by patting him on back. But not effective. He doesn't want to sleep actualy. He plays whole day. He sleeps two.hours in day time. And keep playing. And in night time his desire to play increases more . So when we force to sleep he start crying become obstinate. And takes arround 1 hour to sleep. And after sleeping 1 or little more hour, he sit and tossed here and there change various positions. Like he put his neck on my legs and start rubbing and moving his neck on my body or my wife's body. I observed very closely. He suddenly sits from sleeping and fall in one side to another rolled . And look like he sits in w sitting and put head down on bed and try to rotate while keep fixing head and move his legs. I am unable to understand. No ear problem .
