No judgement. My 2 yo went back in mid June. I also have a 6 yo and my DH is essential with very long hours, so the first 3 months were completely unmanageable. I was working until 1am every night to keep up with my workload. On days when it was impossible to juggle both my not quiet yet 2 yo learned how to work the tablet and put it on youtube. I felt like a failure, but this was the only way that I could meet the minimum requirements of my job, while simultaneously playing teacher.
There was a notable positive shift in my mental health once daycare reopened and the 2 yo never even asks for the tablet anymore.
Do not feel guilty. Just make sure that you're comfortable with the precautions that daycare has put in place.
We're all in this together.
