If you keep feeding your milk, your milk supply will be good. At night, the awakenings are for several reasons other than just milk. May be a bite, itch, stomach pain, wants to play, not feeling sleepy... and the list goes on. We feed from the breast so that it pacifies them back to sleep. Try sitting up and feeding - gravity will help give more milk supply. Feeding mixed milk will cause more gassy issues, plus an unknown cause of colic may be causing the discomfort. It is a phase and will change soon. Infants keep changing everyday. Continue your breastmilk. The more you feed, the more will come. Otherwise pump and give expressed breast milk - you will have an idea of how much milk supply youre getting. Be less stressed and enjoy motherhood The more you stress, your milk supply will decrease.
