I stayed at home for 3 years before our LG was born. But after B was born the only thought that stuck in my mind was how mundane it is. Every 4 hours the same thing, contantly keeping your eye on the clock. For me the moment B woke up the countdown to the struggle for her next nap would start.
In my mind I was just constantly counting (in hours and scoops) I use to hate routine so this is something that I really struggled with. To this day (10 months later) I have to sit in the same room with her, which would be great for you, the moment I leave the room she crawls after me crying but she's fine to play on her own while I'm in the room. So I have trouble cleaning the downstairs because there are places she can't go due to gates.
Upstairs is fine because I can close the gate and she can crawl everywhere I go but yesterday for example I set out 20 things to iron and after 10min she got bored and started tugging on the iron cord.
But for you that's still a couple of months away. I guess as newborns it's easier especially if you have a relaxed baby with very few problems. But they have the attention span of a fish, so it's really not that you can do more than a couple of minutes in the beginning while they are awake and hopefully your baby will be a great sleeper!
Got to go, mine is crying
