I respect single parents that have a rock solid routine with their kids. It is tough. Every time my wife is out of town for more than few days I’m forced to step up my game if I want to keep sanity and order in the house. All the slack time and room for error are removed when you’re solo parenting. You must have a routine that your kids can depend on, and communicate it consistently. There is still free time, but you have to be on top of daily chores. On the upside, you also get a chance to build your relationship with your kids and be highly engaged. It’s a lot of work, but it’s worth it.
