Productivity day-to-day

Hi mamas! FTM here... Advice is appreciated from FTMs or moms with multiple children! For those of you on maternity leave, does anyone else find it extremely difficult to be productive and get things done with baby? My babe is 6 weeks old and it’s been amazing being home with her on maternity leave. Now that she’s getting a little bit older and things are becoming slightly more routine and comfortable, I try to mix in general housework (dishes, laundry, cleaning, etc), plus things like filling out thank you cards for her gifts, organizing her baby clothes, etc. I also work a job coaching a dance team once a week so I have some stuff to do for that here and there. I am finding it incredibly challenging to accomplish anything on my to-do lists! When she’s awake, of course I’m spending time with her.. whether that’s playing, breastfeeding, changing, etc and she basically has my full attention, which is important! When she’s sleeping, I struggle too because she doesn’t have any sort of nap time routine just yet since she just turned 6 weeks. She still just falls asleep whenever. Hoping to try starting a routine in the next few weeks. But in the meantime, I’m either holding her because she fell asleep that way and is comfy and might wake up if I put her down or I’m just taking a breather or I find myself just waiting because I don’t know how long she’ll sleep. Sometimes it’s 2 hours and sometimes it’s 10 minutes. For those reasons, I just find myself sitting around a lot when I finally get “time” or I’m fully occupied with her when she’s awake. Then I get so frustrated later in the day when another day has gone and I’ve gotten nothing done! Any advice so I don’t go crazy and can be a good mom and a productive human?! Ha. As a FTM, I think it’s just a lot of getting used to. I know moms that have more children kind of have to make it work and have more on their plate caring for several kids. Those mamas might have some good tips! Any advice is greatly appreciated!! Thank you 🥰
