Should I delete my mom from my facebook and my life? Shes so negative!?

I don't recommend severing ALL ties with your mom based on the little information I have to go with here, but you must do whatever you feel is right for yourself and your young family. If that means deleting facebook, turning off the ringer on the phone, etc, then that is what you have to do. You said yourself you have two kids both under one year old. They need to be your priority. Either mom understands this or she doesn't. If she doesn't, then she needs to get out of the way or be pushed out of the way. Either way, those babies come first.
