try to lessen slightly his sleep hours during the day at least towards the evening time so he can tune in better to night sleeps
Maybe limit each naptime to less than 3 hours.. baby will not sleep well too if overtired..
My 2m boy is the literally opposite of urs! Hang in there mummy. Fully understand u..
Same as ours. Lately hes been struggling finishing his feedings too at 3oz
Could be colic. Try rub some oil before baby sleeps.
U can play music from YouTube during nite time.
Will get better
