Is it a good idea to..

I’m pregnant with my first , I told my husband I’m thinking of staying at least one month at my in-laws home when baby is here, they are both retired, retired before 65, to have that extra help during the day when my husband goes back to work? I would stay with my mother but my mom still works and also watches my nephew , not sure if this would be a good idea ? I’m worried I’ll get too comfortable there and not want to leave not like they would mind but I don’t know I fear being alone with the child after . I hope this mom thing comes naturally because I feel very not ready and it scares me, at 35 you’d think you would be ready.
