Slight tough love post now.
Nobody is forcing you into using childcare, etc, they are suggesting it as you have a particular problem that lends itself to this as a solution.
My background is that I worked in a nursery for two years, and I also have a degree, a PGCE (i.e. qualified teacher status), a Masters in Education and a PhD in Education, and I actually teach people on early years courses (amongst other things). I have also carried out research and published in the area. Sometimes I offer advice to the Government and other organisations. I also help support early years services in my local area, including helping to run a Children's Centre. So I know an awful lot about children's needs in their early years. Plus I have four children myself, ranging in age from 3 to 25.
I am not in the business of following fashions or having particular hobby horses. I am in the business on analysing all the evidence on childcare and early years education (amongst other things) and coming up with a balanced view. It's what I am paid to do.
As other people have said, one of the worst possible scenarios for a child is to be stuck at home with a depressed parent who does not engage. Perhaps even worse is being stuck at home in a small flat with a depressed parent who does not engage.
There is a well known quotation: "All behaviour is expression". Your children are expressing themselves through their whining. You are unhappy, their mother, so they are unhappy too. You need to address your own frustration and misery in order to sort out their whining and therefore their unhappiness, not turn on us.
Please do listen to the advice you are being given, OP, rather than getting aggressive. We do mean well, and there are some knowledgeable people on here.
