Two hours after feeding overnight (5oz of breast milk and formula) baby was alert and active, he didn't get any sleep. He had spit up more than usual earlier then he started showing hunger cues (lip smacking, rooting, then escalated to some head shaking/hands around mouth) so I decided to give him a go at the breast. I figured he could eat if he was really hungry (was concerned he was trying to soothe a tummy ache or reflux) but it would be slow and we could spend some time before supplementing. We latched on the "easy" left side and he nursed actively for quite a while. I didn't need to coax him, there were a lot of pauses but he kept picking it back up himself. He nodded off a few times but roused and continued nursing. There was a lot of comfort sucking but I figured that would be okay. He broke the latch for good after about 45 minutes and slept a bit. He woke up and I burped him and he quickly became livid, screaming his hunger cry with lots of frantic arm flailing and head shaking. I tried to quickly ease him onto the right side but he had no interest in latching on. Usually I can get a latch even if he's mad but this was a struggle. He latched but never settled down, kept pulling off to scream and pushing my breast away. I tried moving from football to cross cradle then laid back, but he was just not having any of it. I prepared his bottles (1oz breast milk, 2oz formula; which was overly optimistic). I tried to add some pauses in but he was screaming any time we stopped eating. After the 3oz, I tried to pacify him to see if he was still really hungry or just wanting to comfort suck or his brain hadn't caught up with his tummy. He didn't calm down, so I prepared another 1oz of formula and then he was satisfied after eating and fell asleep.
