Hi I've noticed there's no replies yet because lone full time working mums will, basically, not have the time to go on social media!
Don't be ridiculous.
OP it depends on a few things.
Is the job set hours, as in you do x hours a day, but when you finish there's no expectation to do any additional work or check emails etc?
Does nursery provide an evening meal as well for DD? And is it close by to either home (or your workplace if you work from there)?
Do you have anyone who if your litte one was poorly, for example, could help look after her if needed? Managing all of the time off is one of the challenges.
Organisation absolutely is key as you say, I have a few tips:
I used to batch cook on a Sunday whilst DS napped, sounds boring but not too bad with some music on. Pasta sauces, chili etc for the freezer so they could be quickly heated up in the evening. Or plan meals on the weekend for the week and get a shop delivered Sunday night so it's quicker.
My washing basket was the same size as a max load of washing, this made it so easy as I used to chuck it in the washing machine when it was full (all together, i know). If no time in the morning I would leave it by the washer and pop it in as soon as I got home so it was doing whilst doing other things.
Cleaning I used to spend a little bit of time doing a day, and then quick cleans in the kitchen and bathroom every day if needed. Usually a room a day, or sometimes an 'activity' a day ie hoovering.
You'll find what works for you, it probably will be exhausting, at least to start with, but plenty of mums find a balance.
