I mean, my daughter just started to crawl now (4 months old), but watching her when she was 2 months was way more frustrating and difficult because I could not interact with her at all.

She woke up to ear, cried until it was time to sleep, woke up due to dirty diaper, cried again, need to put her to sleep, etc. Then when she slept, I had to clean up the dishes, vacuum, wash her clothes, etc, with barely any downtime.

It was an endless loop with barely any fulfilment.

Once she turned 3 months, things became easier because finally I could play with her, and she would finally start smiling when she saw me, and started acting human overall.

I have no idea how people would think working is harder.
