hi Zennifer, i see some light!! i managed to pat him to sleep tonight!! initially i carried him over my shoulder and pat him, he was obviously tired as he was resting his head on my shoulder. but somehow he just couldn't close his eyes still. since he was very calm, i put him down lying on my bed, i had my arm around him and was lying beside him. i continue patting and singing to him, and he finally slept (probably after 10 mins). i was soooooo happy. even though this may not be the case whenever i wanna make him sleep, but at least it's possible.

thank you so much for your support so far!!
