I've got a few weeks left after DC2 before I rtw and I am dreading it. With DC1 it floored me and took about 6 months to settle back in, I was bloody useless at work and found separating work/home/kids really hard and very unproductive as I WFH.
One thing I have planned with DC2 is a phased start with two weeks at half the normal time whilst I'm still off, so I can be available if they're struggling or poorly. Then my first week back after that will be half days.
I do pick ups and find in so hard to scramble out the door at five if I'm lucky, 40 minutes round trip for pick ups and then sorting tea. Id love to have tea ready the moment we get home but I'm useless at that kind of planning and can't spend my work day preparing food.
Argh it's like permanent Sunday scaries ATM, when I should really be making the most of last few weeks
