OP – a complete bastard would never have bothered to post. You posted because you care, it’s just that you’re overwhelmed by it all at the moment.
ransos on page 4 was spot on – when you’re stressed, put baby down in her cot and walk away. Shut the door, have a brew and come back in 10 minutes. She’ll come to no harm; the person who is more likely to break will be you. That ten minutes is a life saver.
The only advice (which you should ignore!) is don’t take advice from anybody about childcare. Too much conflicting info. Do you’re own thing and you won’t go far wrong.
Good luck, keep us all posted.
Rich.
