I work full time (at the moment, shortly to drop down to 0.8, which is partly because I want to, partly due to budgetary issues). I also have 6 hours of commuting 3 days a week. I work 4 days compressed hours, so about 9.5 ish hours a day. So 3 days I'm out of the house by 6:20am and not home until 7-8pm (last night it was 11pm
) and then 1 day I work school hours and then Fridays are my day off with toddler. I need to drop down to 0.8 (because there isn't money to pay me fulltime at the moment due to funding constraints), but I'll be doing 3 days compressed hours - 10 hours on T, W, Th but I'll have Mondays and Fridays off every week.
If you can manage normal ish working days and stagger your hours with your partner, it can free up the afternoons. So go in at 8am, out by 4pm, have a bit of time with your baby in the afternoon before dinner, rather than the rush home to sort dinner. You don't need two parents home in the morning and if it buys you time somewhere else, then that can make things easier.
Flexibly working helps as well. My days working from home, or shorter days where I work in the evenings means life is less rushed and I get more time with my dc. I personally don't mind the long days and all the commuting because I make the most of that productive time and then take time when they can be home with me.
In terms of organisation, you and your partner just need to think a bit about the week on the weekend. Meal plan and prep where you can. Plan simple, but healthy meals for days when dinner time will be especially rushed. Get life admin tasks done in weekday evenings after bedtime. Make the most of your weekends. I find we don't really have much time on the weekends for anything but family time. We don't see much of friends (we see them periodically but not every weekend or even every month). We don't go off and do whatever hobbies on the weekends. It's time for being together as a family as we don't get that time during the week (dh and I are pretty much only home together to sleep during the week) and we use Sunday evenings to sort out school bags, food, admin, etc. A family calendar helps as well.
It is really not that bad though. I much prefer working to being at home. It's great to have a bit more balance. It also gets much easier as they get older. It's hard to wrap your head around with a 12 month old. It's much different at 18 months or 2 or 3 or 7.
