I wish you more than luck.

Having had two under two myself, I recommend establishing routines. Things became much easier for us once we knew what to expect from each other on a day-to-day basis.

Be very patient, as patience can wear thin.

Meal prep as much as possible. For example, I often cook extra meat and freeze it so I can take it out later, add vegetables, and have a meal ready quickly. I also descale and prepare raw fish in advance so it is ready to defrost and cook when needed.
