Just curious about a few things

Brittany • Mommy to a wonderful 12yr old boy, 9yr old boy 7yr old girl 6yr old girl and 3yr old girl. Due March 11th 2023 with a boy.
1. How many ounces is your 8mth old eating each feeding and how many hours between bottle? My LO won't eat more than 5oz a feeding every 2-3hrs
2. How many times a night does your LO wake for a bottle? Mine wakes twice
3. Is your LO sleeping thru the night?
My LO goes to bed at 7-8p wakes around 1a then 4a then is up by 6:30-7a. 
4. Anyone else LO yell at their sibling when they do something that frustrates them? My daughter gets so mad at her 5yr old brother and will yell at him. And it shocks me. Then she looks at me and cries for me to do something.
