At-home date night after bedtime. Phones away, nice meal, actual conversation. Works far better than going out.

Lunch dates while baby naps in pram - cafes/pubs work and don't need a sitter.

Babysitter circle with other parents - free, reciprocal.

Grandparents 1x a month for sleepover. Date night plus actual rest.

Honestly we just stopped going out and it was fine. They get bigger and date nights return.
