So my mother wants to help with the baby and its appreciated but I'm just at the point I want alone time with my baby. Maybe for a few days to a week to be alone and do this alone, I don't know if its my depression that's causing me to feel this way but I don't even want my ex (child's father) to be here after the baby but I know that'll be selfish of me to even request that. With him being there and my mom (she pretty much hates him) there too it'll stress me out and I'm already to the point where I feel like I'm about to lose my mind some days. All I would really need my mom to do is help around the house maybe or bring food. What should I do?? I don't know if I'll really need my moms help but a lot of people say I will so I said she could help but I don't know if I want her here for my whole maternity leave everyday all day. I feel like I'll never get a lone time with my baby. Advice may help me
