Since becoming noticeably pregnant, my son has taken more of an interest in the sibling he'll soon have.
He'll often grasp my tummy with his hands and blow a raspberry into my belly button. He'll wave hello to my stomach as I go past, and he'll run a car over my bump while I'm sitting to show his brother his best stunt yet.
And his interest doesn't just stop there. He asks questions all the time, which range from the simple "How big is baby now?" and "Is baby coming today?" through to the more confronting "How will baby get out of your tummy?" and "Will he come out of your bum?"
But it's not just him that has taken an interest. His little friends have started to too.
When I picked him up from preschool the other day, one of the boys pulled up my top and shouted into my tummy "Hellooooo in there!" Another looked at me, puzzled, and asked "How exactly DID that baby get in there?" Gulp.
I guess from a child's point of view it is very confusing and strange. To be honest, the thought of a human growing inside a human is mind blowing enough for me.
Still, it's amusing watching the little cogs whir.
Other mums had funny experiences to share too. Benieke told me, "I was in a shop, heavily pregnant, and a little boy asked me 'What have you got in there?' I replied 'What do you think?' to which he replied, quite matter of factly, 'A soccer ball' and walked off!"
"When I was pregnant with my second child, my four-year-old looked at my stomach longingly and said, 'oh I HOPE you have a puppy'," Carly said.
Sara remembered, "When we told my niece, who was four at the time, that I was expecting, she was thrilled - and expected it to be quite immediate. She was a little confused when we explained that she couldn't see the baby 'right now'!"
"I had a little boy at Harrison's daycare say 'Harrison said you have a baby in your tummy. How did it get in there?" Donna said. "I tried to laugh it off, but he was very insistent on me telling him. Eventually I told him to ask his mummy when he got picked up that day - it was the only way I could deter him."
For other mums, their recollections are a little more embarrassing.
"I explained to my son one day how his sister was going to make her exit from my body, and he clearly pondered the logistics overnight," Carolyn said. "The next day when we were in a bank queue, he turned to me and said very loudly, 'Wow, Mummy, your vagina must be huge!'"
Alison recalls a similar situation, saying, "I explained to my two-year-old niece that my first baby was going to be born just after her birthday," she says. "Shortly after, I was out shopping with her and somebody asked me when the baby was due, so I said to my niece, 'When is my baby going to be born?' She bellowed at top volume 'It's coming out your vagina, isn't it?' It stopped me from ever asking a two-year-old a question like that again!"
I am sure that I will have plenty more questions in the months to come, and should probably prepare myself for that as much as I can. But with situations like the ones some of my friends described, my only hope remains that they won't be quite as public!
