my son is 9.5 months old and have similar situation as you (I think for 3 months already). He always cry a bit every few hours and I need to 起身抱起佢或拍佢, 佢先安靜番. But actually he does not wake up (only cry a bit).
I have tried to give him "boyingdan" last week, but no improvement so far. I want to know how to do also.
