Specifically a very young DC.
I'm due soon and all I really see on Mumsnet is the awful of having a newborn 
I don't recall seeing anything good said about newborn/young DC.
I'm quite scared of it all. It's as if the good doesn't always outweigh the bad at all?
In my own experience, I have three very much so younger siblings who've been gold from day 1 really, and never caused many issues.
My DM certainly never went without showering and she never had any help (apart from me, but I rarely stepped in).
Is it really that awful sometimes? That you can't even brush your teeth if you are determined to?
I'm extremely odd about personal hygiene and I would rather someone imprison me and cut off all my luscious locks than someone forbid me from having a shower/carrying out my routine of dental hygiene.
The sleep deprivation is better managed with just one DC to attend to, surely? I can understand the sheer relentlessness of it if you have another DC to run after though.
Honestly, new parenthood just seems a bit shit when you look on MN
