I wasn't sure how much help I would need after having my baby so my mom and dad came down for a week each. My dad just left today and I miss him already. He was so helpful and sweet in every way. My mother on the other hand has only been here for like 3 days and she's irritating the hell out of me. She heated my breast milk in the microwave and fed it to my baby😡 She took him in the bed with her and covered his face with the thick ass comforter. Shes just irritating. I know she's a new grandma but I'm a new mom, and this is my son not yours. Do things my way or leave. She's supposed to be here to HELP ME, meaning assist me in what I need/want done...not control everything. I love her but geesh, she's overstayed her welcome already.
