Quoting Maria + Cory = Alexis:" I didn't realize after only 4 short weeks I am already a failure as a mother. Thanks for the support. ... [snip!] ... trying to defend my mother, she was in the wrong. But making me feel like a horrible mother is not helpful in this situation. "
You are NOT a failure. Don't say that about yourself. You are doing great by just asking what to do and being concerned.
One thing you will realize is your intuition is going to be 99 percent right! Follow it! If you don't think something is right, stop it. You and your LO is the only thing you have control over, don't let someone else take that role from you. I know you have some "Mama Bear" in you somewhere! Use it, chick!
