Some days/weeks, I genuinely do not have time. My DP is away a lot for work, including weekends. I have a difficult 2 year old (sleep-wise) who sometimes doesn't settle until 10pm after battling for 2-3 hours. By that point, I truly am exhausted.
I wake up, get kids ready, nursery drop off, school drop off, use my lunch break at 3pm to pick DS up from school, make him a sandwich, return back to work on my laptop with him at the table or playing, pick DD up from nursery at 5.45pm. By the time we're home, kids fed, kitchen cleaned up, it's around 7pm. Then we begin with the bath/bed routine.
On days where DP is home and can do school pick-up, I'll pick up a lunch time class at the gym and use my break for that, or I'll do a YouTube workout, but honestly sometimes, I prioritise giving myself a break and sitting down at the dining room table to eat my food.
I try my best, but at the moment whilst DC are so small and dependent on me, I have very little "me" time and sometimes when I do get some time to myself, I choose to wash my hair or just sit with a book for 30 minutes instead of exhausting myself further.
