Is it ok for 3mths old to drink milk 170ml only 4 times over 24hr

my 9 mths drinks only 680 to 750ml with the help of syringe feeds at time coz he dont really like to suck after a while... and he can only drink btw 90 to 130 ml each time depending on who's feeding him every 3 hourly... but now he starting to eat porridge with meat fish and veg... it's always a torture to feed my boy milk since born...so normally we result to syringe feed to ensure he takes in minimum fluid to hydrate.... mine 9 mths old boy only 7.6kg

How heavy is your little one? At this age, baby should be drinking about every 3 hours though, and not so much each time
