If both you and your SO work, how do you handle dinner and evenings?

I go back to work in a few months. Right now, DH gets home at 4 and I start making supper at 4:30. By the time supper and cleanup is done it's usually 6:30. We start bedtime at 7.

When I go back to work I want to maximize time with LO when we get home. I'm thinking cleanup will happen after bed and start making easier suppers? We would both be home at 4 as we work together.

How do you do it? 3 hours before bed just seems soooo little.
