It is hard and I'm sorry but childcare is a very different thing .
I assume you don't worry about whether you are setting them up with good thought processes , healthy eating habits , enough confidence to either go to university when they are older or not if that's what they want , are they making friends ? ,does it matter?Maybe they should march to the beat of their own tune ?, do they have good role models? Should I but them xyz because they want it or will I spoil them? Do I work more hours at work to save for their future or spend more time with them? Are we modelling a positive relationship between adults so they see positive ? Was that sneeze being ill or am I overreacting? How much screen time is too much? Should I let them watch so they are up to date with current fads and can make friends or do I ban it ? When do I tell them about santa? Do I encourage magic as a child or tell them the truth ?
Parenting is not childcare , it's for their whole life all the time and it's ridiculous to compare
As for the moaners I'll say that yea of course it's hard...to do it properly and not just baby sit or rock up and keep them alive for a day....yes its hard but I made a choice so I moan a lot less than others because I chose to have my children
It's also so worth it ,best and hardest thing I have ever done
But it's ridicuos and immature to say it intimate you know what being a parent is like being in childcare , having a dog , or having nieces and nephews...you don't
I run children's homes and care services...i don't know what it's like to have a child in care because I have never been there
