Bad idea? *long post*

So i'm thinking super ahead, but I would like to have a plan sooner than later. I'm currently pregnant; with a due date of june19, but seeing as how I delivered my first early (6 weeks) I'm anticipating on a mid/end may baby. My mothers wedding is sept30 making my first born just over 2, and my second 3/4 months depending on their birthday. Both babies are a part of the wedding, but I don't know what to do for the after hours? My son will be going home with my mil, but it's just her at home and she only had one child- so I don't want to put that stress on her with having two babies to handle. Would it be a good idea to ask my dad/stepmom to pick up the baby around 7pm and spend the night at our house? We would be coming home, but much later.. No judging please. I don't want to leave my baby, but seeing as how my mom is almost 50, this will be her only wedding (i assume) and being her maid of honor I feel like I should stay past the dinner/speeches etc. What would you do? If my parents come to our house, the baby will be in an environment it's used to, they'll have everything they need and baby will be fairly young/easy at that point. I trust them 100% I just don't want to be that shit parent😟
