During my maternity leave, I found childcare to be so much harder than I'd imagined; my view on it changed significantly from beforehand. As this was my first child, I had no "mom-friends" in the same situation to talk to, and it was a period of countless first-time experiences.
Although I used to work from morning to night, since I came back from maternity leave I have been working reduced hours so as to not put any burden on my family and children. My day isn't over when I finish work because after that I need to pick up my children from day-care, cook dinner and feed them, bathe them and put them to bed... Fitting everything in is a big challenge, and something I still find tough.
