Crying while falling asleep

When I can tell ds is getting tired, rubbing his eyes, and a blank stare, I put him in his swing. Sometimes he goes to sleep but sometimes he lets out this wimper cry that can get pretty loud but when I go over to him his eys are either closed or almost closed. If I pick him up he is awake but if I watch him for a minute he falls asleep. Its like he is fighting sleep by crying but he is falling asleep. Do you think he needs to let off energy first by crying? I dont like when he fusses or lets out the random loud cry but he is obviously falling asleep.
