Hang in there. Your kids will require less supervision as they grow older. But also the stakes are higher as the potential for emotional turmoil and property damage increase.
I get a few hours after they're in bed and before I go to bed in which to cram cleanup, catching up with my wife, and other bits of essential life maintenance.
It does get easier as they age. Our youngest is three, so I have a while before the "hanging off my legs" phase is done, but I can remember the era of newborns, when I could be interrupted at any moment, and I couldn't count on an entire hour to myself at any point during the day or night.
(FWIW, a big part of making this work is shifting your mindset to appreciate the little things and recognize how precious they actually are. At this point I cherish being woken up by a wailing toddler and rocking her back to sleep, because I know I won't get many more moments in my life when she's a tiny little bundle snuggled up and cozy against my chest, and it's truly magical when I manage not to be hung up on anger over being woken up at 3 AM.)
You have about 1,000 weekends with your kids before they are legally adults. My children are mostly grown up now (18 and 14) and, despite the sleepless nights, I miss having them fall asleep in my arms and their absolute wonder of the world as infants and toddlers.
I appreciate the perspective. I kind of agree with you however my ideas slightly changed over the last year. It is hard to keep spending as much time as possible with kids when you are also trying to make a living and prepare for a better future for them. I think a balanced approach is better for your mental health and also for their future.
