Plenty of people act like Big Mom doesn't like her children or doesn't care for them but I believe that's false, when Big Mom got her memories back the first thing she remembered was her children, not Mother Carmel, and not even food. Some people even try to use the whole killing Moscato and Opera as an excuse but they forget that in those incidents she was on a food rampage, she's not even in her right state of mind. When the food rampages are over she forgets what she did or what she said during that time, yet some people try to use that as an excuse for Big Mom not liking her kids. Also when Big Mom goes on her food rampages she targets everyone, not just her own children but everyone.
Remember when Brûlée got her scar? Some people kept saying it was Big Mom but nope it was some thugs that did that, yet some people still try to blame Big Mom for that too. Remember Katakuri's mouth and how some people kept blaming Big Mom? As we all know it was Katakuri himself who ripped open his mouth because he stuffed way too much donuts in his mouth, and it was Katakuri himself who decided to cover up his mouth.
Remember when some people thought that Big Mom killed Snack? As we all know Snack was never killed just simply demoted, the only child Big Mom ever abused was Chiffon and that's because she looked like Lola. There is just so many misconception when it comes to Big Mom, even Lola herself didn't say anything bad about her.
Big Mom is still a ruthless deranged psychopath but saying she doesn't like or care for her children at all is completely false, she does like and care for them as long as they are loyal towards her and they don't leave the crew.
Even most of her children still care about her, both Brûlée and Oven were very angry at Chiffon for helping Bege out on his assassination plan. When Big Mom's children saw that Bege tried to kill Big Mom all of them such as Mont-d'Or were very angry, even non children subordinates have been shown to be very loyal despite some fear towards her. Tamago wanted to do everything to prevent Big Mom's name from being tarnished, and Pekoms even refused to help Bege out on his assassination plan.
