YABU
I have 3 small children, the youngest is nearly 4 and I only feel now like I might be able to find me again.
DH and I both work full time, so I drop at nursery, then at school breakfast club, then drive fast (in between traffic) to hope you get to work on time, walk very fast for 15 mins from car park to work, do my job til 5pm, run back to car park, drive fast home, hope there are no delays, rush to after school club, drive round to nursery, drive home, feed, homework, sort animals, wash children, bed, stories, out wash on, full dishwasher, empty it, make lunches for next day, go to bed exhausted
Youngest still wakes over night unfortunately and they are up again at 6am
There is no time for exercise, DH works long shifts and often weekends. I breastfed each until they were 12 months old and none would take a bottle so that limited me before going back to work too.
Thankfully my friends waited for me.
