Try baby wearing him for skin to skin and even nurse him, sometimes they just needs to be close to feel the warm and the smell of the mother, when you baby-wear him, he will feel like he is in the womb and would feel much safer, once he quiet down, you can wear him and sit with hands-free.

Also for wind, next time try doing 'cycling' with his feet and massaging his tummy before bedtime, you will see that he will burp. Don't put him down to sleep straight away, just wear him for awhile

Also, if he sleeping with you on the bed or in a cot? You might want to try to let him sleep under your armpit area - this has proven to make baby feel more confident and secure when they sleep, to have your warmth and smell nearby.

Don't wait for him to wake up and cry for milk, set your alarm slightly earlier than his feeding him, once you see him to have tongue out or mouth twitching, you can nurse him before he cries, coz once he cries, a lot of wind would have gone into his stomach causing discomfort

is it the bottle? Do you feed bm with the same bottle? if not maybe the teat of the FM bottle is not suitable causing wind/colic and he gets tummy upset after feeding..maybe la I don't know..did you burp him after feeding?

Maybe after feeding dont put him down straight away, carry him upright or slanted and keep tummy area warm.

Also my grandma used to tell me that kids are more sensitive to supernatural beings, it's the hungry ghost festival now, maybe don't take him out once sun starts to set (grandma said i just follow)

Erm..2mths old cannot see la...blur vision...maybe just wind in stomach

Not pat directly at the back but towards the sides with yourvhands slightly cupped. You can aldo do cycling with his legs. This will make him fart or burp.

Another thing is to massage the body n tummy after bathing
