"That's not food!", usually said whilst frantically trying to scoop sand/Miracle-Gro/Pritt Stik out of DS's mouth.
"Baby doesn't want to say hello right now, sweetheart" - DS keeps lifting my top right up (and I mean right up) to say hello to my bump. I can safely say that most of the staff at Asda, Mothercare, Primark, and Boots have now seen my bra.
"That's your belly button ... Don't put the straw in it".
"Get the dog out of your mouth!"
(overheard when DS went to watch DH pee) "No. No .... NO!! Daddy is trying to wee, I don't want an empty toilet roll tube on my willy! .... AAARG!!! Let go! LET GO!!" (DS had apparently tired of the tube and grabbed himself a handful of ball instead).
"Why is there juice in the washing machine?"
"Get your bum out of my face."
"It's okay to sniff your own shoes if you desperately must but please stop sniffing the display ... And give that girl her shoes back! No, don't sniff them!"
"Get down!" x100000 times a day
"Put Santa's ornaments back! And that log! And those carrots are for the reindeer ... Sorry about this, Santa ... Are you going to say hello to Santa Claus? Oh ... Bye then, Santa"
