Good luck Kylz! A few things that helped us were having lighter dinners when the kids had cooked lunches at cc (especially when they were your DS' age). We'd often do sandwiches as they were tired and wanted to hang out with mum. I cooked a few meals on the weekend and stocked up the freezer to make the evenings easier. Also we packed bags and lay out clothes at night (for everyone) as it made the mornings much easier.
I also tried to remember what we were aiming for with me working and had a few treats booked in so we all enjoyed our family time on the weekends. Plus the odd coffee during the week, lol! xxx
