So hubs and I are on a BBQ team and there’s a bbq competition coming up in a few weekends and we have a chance to make some extra money. My mom is willing to watch our little guy. It will be for a few hours on Friday and a few hours on Saturday. I’m tore bc we need to do it for the money but I hate leaving little guy. Plus I feel like I’m putting my mom out bc she will have to change some plans of hers. But she offered without me asking and keeps telling me she don’t mind and it’s to make money.

What should I do?
