Maybe I’m overreacting

I had my baby March 28th, and my partners mom came to move in, but she is going back to where she lived in July. My partner thinks I need help with our 4 kids and I don’t I’m their mother I can take care of my kids on my own their MY KIDS, and don’t get me wrong I appreciate the help while she is here, but sometimes I feel she just oversteps boundaries when it comes to my kids and I know she tells my partner things in my Spanish how I should educate my kids and take their uniforms off when they get home from school and put something else on them and I’m not doing that I like to give them a bath first before putting on clean clothes! Well my partner is leaving for Drill in June and usually when he is gone for 2 weeks I go see my family and stay and now I can’t cause I have to stay here with his mom because I’m her only transportation and it makes me sad. My kids are out of school for the summer and I can’t go visit my family now while he is gone. I’m sorry just venting I’m 6 hrs away from my family and no family where I live.
