Yes you can. However maybe you can slightly increase the scoop. Example : Dulac brand - 2 scoops, 60 ml, 8 times of feeding. You may change according to the needs of your baby. Usually FM can make a baby full. It can also be due to upset tummy, uncomfortable due to adjusting to the new environment therefore he wakes up. So maybe you can make slight adjustment to feeding and see if there's changes instead of feeding him 50 ml and thereafter 1 hr gap another 20 ml and then another 20 ml. It will be inconsistent.
