In my late 30s and I find it increasingly difficult to concentrate on stuff - whether it is conversations that last forever and perhaps I am not interested, remembering stuff - what on earth did I intend to do just now? -, starting one thing, jumping onto something else and then ending up with 10 things half done. I know many mums talk about similar feelings. What's normal for you?
Some aggravating factors I observe:
The long to do list, growing but the second in the back of my mind.
General stress about stuff / life.
DCs and DH constantly talking all at the same time, always needing attention or something different.
Sleep - I always wish there was time for more. DCs wake up on the odd night (say once a week). The only time available I find for chores is after their bedtime and before mine...
