Hi girls. Is there anyone here who went to work when their child is under two years old? The situation is that I want to go to work, in kindergarten we're still early, they take them at 2 years old, I agreed with my mother-in-law that she would sit with the daughter while I'm at work. She lives with us, there will be no inconveniences for her, but I worry about whether she can cope... Our daughter is very active, always watching her, but when I have to leave for a couple of hours, my mother-in-law manages. Today was her trial day, which she didn't pass ? Tomorrow is my first working day, and I'm so nervous
