I think I may generally be the "wrong" person for this thread though as I'd been a nanny before having dd so was pretty confident on childcare...
Ex on the other hand dd was the first baby he'd EVER held and he constantly worried he was going to do something wrong!
Reason I mention is bathing in 2cm lukewarm water
Having had a c-section I found using the baby bath a pita! So as we had a good sized kitchen sink at the time I found it easier to bath her in there.
Ex's first time bathing her this way resulted in total panic stations! Why! Cos he accidentally knocked a sharp knife from the drainer into the sink panicked and caught the hot tap while trying to fish it out - then panicked about that too and tried to whip dd out the sink but she was covered in soap and just slid back in! 
He was a nervous wreck and wouldn't bath her again that way...she was absolutely fine! Despite the knife and "flame" juggling 
Ahh yes, I did once freak at my brother for giving her an UNCUT grape once - as did rest of family! He wasn't a father at this point and didn't know the recent (then) advice on this
I just watched parenthood (the movie) again and I do love the line about letting the 3rd kid juggle knives!
In terms of experience dd was about my 20th! But exs 1st.
Ohh just remembered the time I forgot ALL my training and experience...
When she was moved into her own room around 9/10 months old and her sleep went to shit!
We tried everything (we thought) but mainly we were VERY careful to make ZERO noise when she was finally asleep for dread of waking her!
I'm talking tv on mute and subtitles on, no "pottering" upstairs, only using the downstairs loo...and still not flushing unless absolutely necessary, closing the kitchen door before boiling the kettle....!!!!
We couldn't understand why she was COMPLETELY freaking out when she did wake up "but we were so quiet!"
Well...turned to my mum for advice, exhausted, wired, nerves wrecked...
And she laughed!
At first I was most insulted then she gently not reminded me of my experience/training and told me we were idiots! That the baby was freaking because that total silence made her think we'd disappeared, that we'd abandoned her!
So we (nervously, not entirely convinced) went back to normal noise levels even gradually adding in doing "noisy" things like running a bath and having music on for said bath...
Dd settled better at night and stayed asleep for longer periods
D'oh!!
