I'll add my story here even though things have changed recently plus I recognise it's easier for us as we only have one child.
I went back to FT work when DD was 10 months old. I found a fantastic mother-daughter CM duo who look after DD from 8.30 to 6pm. DD settled in immediately - no tears, not even on day 1, and has thrived in this home-from-home environment. She's a very happy little girl.
DH, DD and I survive on strict routines. When I used to commute: All up at 6.30am, I'd put load of laundry on if needed on 1 hour cycle for DH to put on tumble or on line or on clotheshorse an hour later, DH gave milk and got DD ready and I jumped into shower, then I gave DD breakfast whilst DH got in shower and I also got ready for work. I left house by 7.45 and at my desk by 8.15/8.30. DH dropped DD off at CMs at 8.30 and went to work.
I left work at 5 to collect DD by 5.30/5.45pm and we were home by 6pm. CMs gave DD her cooked lunch and dinner. Once home, I played with DD, got her ready for bed and she was in bed for 7. Then I got dinner ready (we always menu planned and shopped on the weekends). Weekday meals sometimes cooked in advance on weekends and frozen or else stir fries so evening meals very quick. I was often relaxing (or working again) by 8pm and we ate when DH got home around 9pm. Our bed around 11pm.
No housework at all during the week except quick wipe of toilet and kitchen surfaces and general quick tidy up of stuff. All cleaning/housework/hoovering/bedding-laundry kept to weekends, first thing Saturday equally split between DH and I and all done within an hour (largish 3-bed house), menu plan for week and shop (online too) then do as we please all weekend. DH irons his shirts on Sundays when DD is having her dinner at 5pm.
I now work from home so no longer have to commute and mornings no longer a rush so I can spend more time with DD one-to-one before DH takes her to the CMs at 8.30. Still keep housework for weekends, but laundry can be done at leisure.
Works for us and always has worked for us. I didn't have working guilt either because DD was so obviously loving being with the CMs.
