No she’s not 
Ok she is but you know that she never means that in a negative way. I am not sure what specific example you have in mind, but I will mention one example:
When I used to come home from work and tried to go to kitchen to get something to eat (which is my habit because I get my own food instead of expecting it on the table), she would always stop me and ask you to get up and give me dinner (in a nice way). Or when you would wake up late on weekends and I used to be up before you, she would offer to make me breakfast but I would turn down the offer and wait for you. Again, she does not think ANYONE can care for her kids more/better than her and that’s juts any mom. It applies a bit more in her case because she raised 4 children in Pakistan all by herself while her husband was earning money for the family in the US. That’s why she’s extra protective.
She’s like that with anyone, remember when dad tries to daant us and how she jumps in the middle and takes the blame and calms things down? I miss my mommy
