In my experience (parent to a 4 year old), I was overwhelmed with what I thought it took to be a good parent. There are lots of "recommendations" given to new parents about things to do for their babies. I can't even begin to list all of the suggestions there are just so many. Thankfully, I quickly realized a few things: (1) I don't have the time or desire to do everything and (2) you don't need to do everything there is to have a happy and healthy child. It's like, parenting can take up every single minute of every single day if you want it to, but it doesn't need to.
So, what does that mean for our family (2 full time working parents)? It means that our child goes to day care, and spends time with his grandparents (both sets of GPs live locally), he spends time with only one parent (to give the other a break), he spends time with his cousin (we return the favor and watch my nephew too), he watches TV occasionally (to give both parents a break at the same time!), he goes on play dates with other kids (this is also reciprocated), and he also spends time entertaining himself IN ADDITION to the things we do together as a family.
I'll also say that, again in my personal experience, being a parent is much more fun than I had thought it was going to be. I guess that I heard a lot about how time consuming and tiring it was going to be. And it is, at times, but (again speaking from my own personal experience) it is not as terrible as I had been led to believe!
Also, it seems to be getting easier and easier as our son gets older. Sure, he's a more complex human being but a lot of the day-to-day tasks he can do himself now- i.e. he is potty trained, he can dress himself, he can entertain himself coloring or playing with books and stickers for periods of time, he can feed himself, he sleeps at night, he can communicate his wants and needs clearly, and so on.
