This just happened... literally seconds ago.
Not accidentally - I can still remember having baths with my mum as a young boy. Our old house had awful plumbing and it used to take about an hour to run a bath, so mum used to share them with me to save huge amounts of time and aggro. I am talking age 4 or 5 here
None at all
She nursed my brother next to me. Made me excited and anxcious, but @ 3 had no idea whay.
