My daughter had reflux and I used to feed 1.5 ounces of food, burp in sit position with y position on head and circular back motions and then feed 2-3 ounces and burp again after this I would put her in a bouncy for 30 minutes to play after feeding and even before bed on vibrate to sooth and keep the food down. This was all ways to avoid the throw up, feeding slowly instead of letting her chug it down like she wanted to do helped tremdously. burping in between as well as the incline right after feedings was key. At night had incline on bed as well and mylocon drops here and there. I used paci's for sleeping until 18months and this was a soother for the oral fix instead of feeding as they weren't able to self soothe and weren't hungry just wanting to suck at night to go back to sleep. Paci's are so controversial for some reason, they insured my babies and I got our sleep and now without pacis are healthy still good sleepers. Sleep patterns are key at even the earliest stages to good sleepers for long term. I had maybe 4 pacis around their heads at 5months so they could find one at night and a lovey(a felt, no hard eyed stuffed animal) in their crib for a transitional object. My daughter preferred a teether pal and still has it at almost 3yrs. and son a felt Tigger.Sometimes they're hungry sometimes they are crying from gas build up from too much air bubbles. Crying is hard to figure, I would not feed in the middle of the night as past 3-4 months they should be sleeping 6-8 hour stretches for you, they respond to what they expect, if they think you are going to give them food at 2-3am then they'll eat it, if you burp them for excess gas, shhhh them with them still lying down (not picking them up), give them a lovey or paci instead they can accept that too and change pattern of their expectations in the middle of the night. Much quicker to reaassure them in the middle of the night with a shhh, soother (paci or lovey) and a quick check of burps and go back to sleep as a mother than do another feeding in the middle of the night.
As they grow they will cry for different reasons (when they are sick, night terror, growth spurt and such, my consistency of reassuring I am here for them in the middle of the night for a brief moment shhhhing them, rubbing their back, giving a dose of medicine or whatever still now is quick fix and back to sleep for both of us to this day with my kiddos. They don't expect long soothing/rocking in the middle of the night so we both get more rest and they get reassurance or need met but rest the most important thing we both need.
Best Wishes its such a cute baby age 5months to 10months Enjoy them they grow so fast.(:
