Birds and the Bees, I also answered questions when asked and used correct terminology - my DH is a professional naturalist so we often were asked about the various insects etc reproducing. My neighbour is a little straight-laced and I was talking to her over the garden fence when my 4 year old DD, who was sitting by our garden pond, shouted up the garden - come quick mummy there are two frogs copulating. My neighbour was horrified.
My DS4 asked my darling MIL if she also had a 'gina like mummy. She was mortified. We were told off for teaching him 'such' words.
Again my DGS aged 3 only the other week asked me if I had 'tentacles' I answered no only boys and men had testicles.He then asked him mummy if daddy had some -Yes - did uncle G have them - yes, this went on for about 10 minutes. He then said has my grandpa (who he calls 'my Brian' got tentacles? I said, without thinking and wanting to get to the end of the 'game' - you had better ask him. At that he ran to the open patio door where Grandpa was talking to the afore mentioned neighbour and shouted "My Brian, have you got tentacles too?" I was surprised the neighbour did not faint.
The taking toddlers into loos also had me. I was in the town with my 3 year old DGD when I was taken short. We went into the ladies, she used the loo then it was my turn. I was sitting down and took a pad out of my bag. She said in a voice only 3 year old girls possess GRANDMA MY MUMMY PUTS THOSE SORT OF NAPPIES ON MY BROTHER, it must have been 50 decibels. I too came out of the toilets furtively.
