200ml seems a bit too much? But did the pediatrician say anything when you went for your baby checkup? I guess, if he finds it okay then it's fine. And having the 200ml, does he vomit out the milk later? If yes, then he's being overfed..
my baby is also 2mth old now, about 5kg (but at birth was 3.12kg - so i guess also depend on what weight yr baby starts with). he's drinking 140ml during the day and 160ml during the nite. Like you, we used to also feed him at every screaming and he will still drink (sigh) though pple said they will know when to stop - but he doesn't and later he'll vomit out the extra milk. But now we realised that sometimes after feed, he still cries... is not crying for milk.. he could be tummyache or wanna burp. So after feed, i'll carry him upright position to burp and not sure if parents here will encourage.. but i do walk him around the house in upright position to burp him. I think with our movement, he bounced a little and making him burp faster/easier. But sometimes when all these fails, i'll make him another 60ml to see if he can finish.. sometimes he does (and continue crying.. faint)... but most of the time, he will just doze off after some suckle.
And I bought a rocker/bouncer for him - after feeding and burping - if he still fusses around.. he could be sleepy, butjust couldn't sleep... I'll place him in the bouncer and gently bounce him. my boy doesn't like to be swaddle when he's awake (if yrs ok, you can try swaddling) - I'll place the cloth diaper on the bouncer and open up before placing him down.. then i'll hold his 2 hands by the side to preven him from swaying his hands.. and start bouncing him (gently) until he's blur... then i'll use the cloth diaper to swaddle him. With that he can nap at least 1.5hrs - 2 hours... :P
you try... i also went thru a hard time during my initial months... zzzz
